Where Can I Download the PID Controller Tuning for a Buck Converter Example?
Hello,
I’m interested in learning how to tune the gains of a PID controller for a buck converter using Simscape Electrical™. I came across a video that demonstrates this process and explains the new frequency response-based PID tuning method introduced in R2017b.
Here is the link to the video: PID Controller Tuning for a Buck Converter
I would like to download the example file or model used in the video. Could anyone provide guidance on where I can find this example? Is it available for download directly from MATLAB Central, or should I look elsewhere?

MS Defender for MAC OS do not generate alert when I download malware
Hello!
I have the latest version MS Defender for Endpoint (MAC OS) with the last update. First I try to download any malware from test malware repos (like https://objective-see.org/malware.html). But when extracting files from the archive, Defender does not generate any alerts. Why?
But if I made a scan folder with MS Defender after extracting, MS Defender alerts work OK.

How do I damp a membrane subject to a time-dependent force with PDE Toolbox
I have a membrane wave equation simulation using PDE toolbox functions with time-independent but spatially constant or varying m and c. I can excite it with a a time dependent edge boundary or with a time and space dependent f. WIthout f, I can Rayleigh damp an initial state using the M and K matrix for in the documentation (I cannot set d= constant, consarnit, nor is it at all clear how to make the damping expressed in terms of node space dependent.) Anyway, when I during on damping with a nonvanishing f I receive the following error: after the followign code. Any advice/help resolving this would be appreciated as I can’t find in the documentation any example or advice.

How to regrid 2 surface data to match each other
Hi,
Soo I have been going on for a bit with this issue. I have a set of wind data for the Australian region that I want to process. This data includes longitude, latitude, and wind speeds in both the x-direction and y-direction. Specifically, the x-direction data is represented by ulon, ulat, and uwind, while the y-direction data is represented by vlat, vlon, and vwind.
I want to calculate the resultant wind speed using the Pythagorean theorem. To do this, the dimensions of the u and v data need to be aligned, which is not the case currently.
How can I write a script to regrid the data so that the dimensions of the u variables match those of the v variables. And for a single lon/lat pair there should be a uwind and vwind.
The results should be stored as rlat, rlon, and rwind, where rlat and rlon are the regridded latitude and longitude, and rwind is the resultant wind speed.
thanks in advance.Hi,

Integrating Workload profile Container App with Front Door and Application Gateway Private Link
Introduction
For the workload profile container app, private link support is not yet available. This is because the “Private Link Service does not support a load balancer that has an IP-based backend pool, which is used in Consumption + Dedicated environments (Workload Profile)”. Although we have a roadmap to implement this feature (Private link support for Workload Profiles · Azure Container Apps Roadmap), there is currently no ETA.
In the meantime, I will guide you on how to integrate a workload profile container app with Azure Front Door using an Application Gateway. The architecture involves using the Application Gateway private link to connect to the Front Door, and placing the Application Gateway in the same VNET as the container app to achieve this integration.
Note: As of August 2024, the private link for integrating Application Gateway with Front Door is still in public preview. Please avoid using it in production environments. For more details, refer to the documentation: Secure your Origin with Private Link in Azure Front Door Premium | Microsoft Learn. You can also check the document to see if it has reached General Availability (GA). Once it is GA, it will be safe to use in production environments.
Instruction
1. Create Container App with workload profile in the internal VNET
This step is straightforward. Follow the official documentation here (Integrate a virtual network with an internal Azure Container Apps environment | Microsoft Learn) to create a new internal Azure Container App environment in the VNET. Here are a few important points to note:
(1) When using the workload profiles environment, ensure you have a /27 or larger subnet
(2) After creation, enable Ingress for “Limited to VNET” to allow Application Gateway traffic to reach the container app
2. Create the Application gateway in the same VENT as Azure Container App
Follow the step-by-step official document here (Protect Azure Container Apps with Application Gateway and Web Application Firewall (WAF) | Microsoft Learn) to create the Application Gateway in the same VNET as your Azure Container App. Here are a few important things to note during this process:
(1) Create a Private DNS Zone for the Container App’s default FQDN. This ensures that the Application Gateway can properly resolve the Container App’s FQDN
(2) Prepare a custom domain and certificate for the Application Gateway. This allows the Front Door to set up a private link to the Application Gateway’s custom domain using HTTPS
Once you’ve completed Steps 1 and 2, head over to your specified custom domain to check if the connection between the Application Gateway and Azure Container App is working smoothly.
3. Create Azure Front Door and integrate with Application Gateway via private link
When I wrote this blog in August 2024, the Azure portal still did not support integration with Application Gateway. (Secure your Origin with Private Link in Azure Front Door Premium | Microsoft Learn) Therefore, we might need to use Azure CLI commands to achieve this. Please follow the steps 3-1 to 3-7 to finish the setup.
3-1. Create an Azure Front Door Profile
Important Points to Note:
(1) Ensure you are using the Premium SKU.
(2) Create the resource group first, or you will encounter the error: InvalidArgumentValue: Missing required field: –location
az afd profile create –profile-name <profile-name> –resource-group <RG-name> –sku Premium_AzureFrontDoor
3-2. Create endpoint
az afd endpoint create –resource-group <RG-name> –endpoint-name <endpoint-name> –profile-name <profile-name> –enabled-state Enabled
3-3. Create origin group
az afd origin-group create –resource-group <RG-name> –origin-group-name <origin-group-name> –profile-name <profile-name> –probe-request-type GET –probe-protocol Https –probe-interval-in-seconds 60 –probe-path / –sample-size 4 –successful-samples-required 3 –additional-latency-in-milliseconds 50
3-4. Manually Adding Private Link Configuration for Application Gateway
When adding a private link configuration, keep these three points in mind:
(1) Create a New Subnet: Ensure you create a new subnet specifically for the private link.
(2) Select Frontend IP: Choose the Frontend IP that is connected to the listener.
(3) Save Frontend IP Configuration: Save the value for “Frontend IP Configuration” as it will be needed for the parameter –private-link-sub-resource-type in the next step.
3-5. Create origin and integration with Application Gateway private link
az afd origin create –enabled-state Enabled –resource-group <RG-name> –origin-group-name <origin-group-name> –origin-name <origin-name> –profile-name <profile-name> –host-name <custom-domain-name-for-appgw> –origin-host-header <custom-domain-name-for-appgw> –http-port 80 –https-port 443 –priority 1 –weight 500 –enable-private-link true –private-link-location <location-for-application-gateway> –private-link-request-message ‘AFD application gateway origin Private Link request.’ –private-link-resource <application-gateway-resourceID> –private-link-sub-resource-type <frontend-ip-configuration-name>
3-6. Go back to Application Gateway and approve Private link request
3-7. Create route
az afd route create –resource-group <RG-name> –profile-name <profile-name> –endpoint-name <endpoint-name> –forwarding-protocol MatchRequest –route-name route –https-redirect Enabled –origin-group <origin-group-name> –supported-protocols Http Https –link-to-default-domain Enabled
Congratulations! All the steps are complete. Now, you can try accessing the Azure Front Door default domain to ensure everything is working perfectly 🙂
Additional Suggestion
To ensure that the Application Gateway only accepts requests from Azure Front Door (AFD), you can use a Network Security Group (NSG). Follow these steps:
(1) Create a new NSG
(2) Add a rule to allow traffic only from the source (AzureFrontDoor.Backend) for port 443
(3) Add another rule to allow from source (GatewayManager) for port 65200 – 65535 *This is needed for Application Gateway to working
(4) Navigate to the Application Gateway subnet and attach this NSG
This will lock down access to the Application Gateway, allowing requests only from Azure Front Door.

Introducing new OneDrive, Quick Links and Playlist cards for Viva Connections
Viva Connections is the one stop place for all employee service where employees can easily access the relevant company information and their personal tools. We keep on evolving and improving the Viva Connections experiences constantly with new out-of-the-box features and on new extensibility opportunities .
We are excited to announce the availability of three new out-of-the-box cards, which are available to be used within the Viva Connections dashboard. These cards are a OneDrive card (files), Quick Links card and the Playlist card.
These new cards are demonstrated in the following video with Pooja Gulati (Microsoft) & Vesa Juvonen (Microsoft).
OneDrive card
The OneDrive card is one such card which appears out-of-the-box without any configuration by the operator (Viva Connections “administrator”). It is a user-based card, and the end user can access the recently accessed, shared, and favorite files from this card. This OneDrive card gives a quick and straightforward way to access commonly used files by the user directly from the dashboard. Files are automatically opened in the most suitable solution in desktop, tablet and mobile devices.
This card is associated with Microsoft 365 Roadmap ID 388496.
Quick Links card
Quick Links card is used to expose relevant links for the end user. The operator will set up a list of commonly used links by the user based on their role or company objectives. Especially in the case of frontline workers, this comes handy as they are on the go and need relevant information easily accessible through their mobile devices. Quick Links card can be configured for a particular department, using audiences, which then enables relevant links specific to department employees or teams.
This card is associated with Microsoft 365 Roadmap ID 402189.
Playlist card
The Playlist card displays a list of video files listed in a specific playlist. This card can be, for example, targeted for new employee onboarding which covers a list of videos which the employee should view to complete the onboarding process of the organization. This could also refer to a group of videos to handle a security audit or certain announcements for an event or trouble shoot parts of an appliance. This card needs explicit configuration by an operator and videos can be made available with audience targeting in place if needed.
This card is associated with Microsoft 365 Roadmap ID 402190.
Frequently asked questions
When are these cards available?
Cards are gradually rolling out in the summer/autumn 2024 timeframe. Each card will be enabled one-by-one for customers, so you can expect them to be fully available within autumn 2024.
What do you need to prepare?
There is no need to prepare for these features as they will be simply available in your tenant automatically. If you have already enabled Viva Connections in your tenant, cards will be available for the operators in the dashboard editing experience, as they are enabled.
What is next?
Lot of new features in the roadmap of the Viva Connections. We are working on numerous new features to improve the Viva Connection experience based on customer and partner feedback. Your feedback and input are invaluable on building these experiences. Got an idea or feedback? – Please add comment below or use the Microsoft Feedback portal.
Thanks for reading. Please enjoy the new configuration options and let us know any feedback or questions in the comments.

Motor drive efficiency and power
Hello Everyone,
I have modelled a 3-phase motor drive, and now I would like to calculate its input and output power for the purpose of efficiency calculation. I am using a power sensor at the DC side in which I am averaging the power at every 0.001 sec, and using a three-phase power sensor at the inverter’s output. The issue which I am facing is that the inverter’s output power is somehow higher than input power, approximately 10 times higher. Could you please provide your insight on how do I rectify this issue, or what could the problem causing this? For three-phase power sensor, the settings are set at balanced load.
Moreover, I am also using a mechanical power sensor at the motor end to calculate mechanical power, and in order to calculate overall efficiency of the drive, i would normally divide the output power by input power. I have saved the scope data and transfered it into excel, where when I performed division between output and input, i get different efficiency values for different points which is expected, but at some points, the efficiency is more than 100% apparently. Could you kindly provide assistance on how should I approach this issue to find effciency? should I average the vlaues first?
The scope screenshot is hereby attached.
Note: A drivecycle is used as a reference that is why there is no output until 20Sec.Hello Everyone,

Logo Builder not available with Partner Launch Benefits?
This year we switched from using the Microsoft Action Pack to the Partner Launch Benefits pack. I was surprised to learn that the Logo Builder is *not* included in Partner Launch Benefits.
Is there some rational reason why this is the case?

Cannot create UdpPort for specified LocalHost and LocalPort
I want to receive Ethernet data through udpport，It was up and running yesterday。
u=udpport("LocalHost","192.168.33.30","LocalPort",4098,"OutputDatagramSize",65507);
Now when I run it, I get an error：
ERROR: Unable to bind to LOCALHOST and LOCALPORT. Verify that the LOCALPORT is not in use, and that LOCALHOST and LOCALPORT are valid for IPADDRESSVERSION "IPV4".
I change different localport and localport，and I even restarted the computer, but still reported the error,I checked the port through cmd and there was no process。I hope to get an answer。I want to receive Ethernet data through udpport，It was up and running yesterday。
