I have some issues with derivating D-Q inductance from a five-phase FEA data.
Hi folks,
I have simulated a five-phase interior PMSM on FEA software to get self and mutual inductance data. The data have been calculated according to mechanical rotor angle (half of the electrical angle in my case). Now, I want to calculate d and q inductances. As you know, there is a five-phase coordinate transformation block in Simulink and one can easily get the equations from the block help page. The equation is given below. However, when I calculate the d-q inductances by electrical rotor angle the results are not constant. The results formed a sinusoidal wave shape. Is there anyone familiar with such calculations to help me figure it out?
Thanks for your help in advance!
The code:
a=length(e_deg);
Ld=zeros(a,1);
Lq=zeros(a,1);
for ind=1:a
Ld(ind,1)=(2/5)*(sind(e_deg(ind,1))*Laa(ind,1)+sind(e_deg(ind,1)-72)*Lbb(ind,1)+sind(e_deg(ind,1)-144)*Lcc(ind,1)+sind(e_deg(ind,1)+144)*Ldd(ind,1)+sind(e_deg(ind,1)+72)*Lee(ind,1));
Lq(ind,1)=(2/5)*(cosd(e_deg(ind,1))*Laa(ind,1)+cosd(e_deg(ind,1)-72)*Lbb(ind,1)+cosd(e_deg(ind,1)-144)*Lcc(ind,1)+cosd(e_deg(ind,1)+144)*Ldd(ind,1)+cosd(e_deg(ind,1)+72)*Lee(ind,1));

flickering lamp with visual effects in simulink
Hi,
I’m trying to simulate a lamp connected to an electrical system that suffers from flickering voltage in simulink. The lamp light should show flicker in a visual manner. Any idea’s if this is possible or how to go about it?
Please, assume here that lamp is a resistor therefore when the voltage changes the energy flowing in changes as and a result the light loses or gains intensity. So a simple way to regulate the intensity of a monocolored lamp in simulink should do nicely.
If you have more knowledge regarding this topic please answer the following question as well.
In a broader sense is there a way for example to simulate a tungsten filament lighting up or any other phenomenon, assuming you have the equations governing it (supposing you can solve it with finite element or what have you), with visual effects?

Problem with ‘Patch’ graphics in 2014b – Splits in two along diagonal
I’m using ‘Patch’ to replace the boxes in box plots to change the colour etc. Code is:
h = findobj(gca,’Tag’,’Box’);
for x=1:length(h)
boxShade=patch(get(h(x),’XData’),get(h(x),’YData’), colours(x,:), ‘linestyle’, ‘none’);
uistack(boxShade,’bottom’);
end
delete(h);
This worked fine until I updated to 2014b where now the Patches appear to split in two along the diagonal, with the median in front of one half and behind the other. Example cut from exported pdf:

I am using the painters renderer as I’m outputting vector pdfs.
Any ideas? I’ve seen some other talk that it’s a bug from intersecting lines in a patch but there are no intersections here I believe as it’s just a simple rectangle?

Introducing Core AI – Platform and Tools
Satya Nadella, Chairman and CEO, shared the below communication with Microsoft employees this morning.
As we begin the new year, it’s clear that we’re entering the next innings of this AI platform shift. 2025 will be about model-forward applications that reshape all application categories. More so than any previous platform shift, every layer of the application stack will be impacted. It’s akin to GUI, internet servers, and cloud-native databases all being introduced into the app stack simultaneously. Thirty years of change is being compressed into three years!
We will build agentic applications with memory, entitlements, and action space that will inherit powerful model capabilities. And we will adapt these capabilities for enhanced performance and safety across roles, business processes, and industry domains. Further, how we build, deploy, and maintain code for these AI applications is also fundamentally changing and becoming agentic.
This is leading to a new AI-first app stack — one with new UI/UX patterns, runtimes to build with agents, orchestrate multiple agents, and a reimagined management and observability layer. In this world, Azure must become the infrastructure for AI, while we build our AI platform and developer tools — spanning Azure AI Foundry, GitHub, and VS Code — on top of it. In other words, our AI platform and tools will come together to create agents, and these agents will come together to change every SaaS application category, and building custom applications will be driven by software (i.e. “service as software”).
The good news is that we have been working at this for more than two years and have learned a lot in terms of the systems, app platform, and tools required for the AI era. To more rapidly and boldly advance our roadmap across each of these layers, we are creating a new engineering organization: CoreAI – Platform and Tools.
This new division will bring together Dev Div, AI Platform, and some key teams from the Office of the CTO (AI Supercomputer, AI Agentic Runtimes, and Engineering Thrive), with the mission to build the end-to-end Copilot & AI stack for both our first-party and third-party customers to build and run AI apps and agents. This group will also build out GitHub Copilot, thus having a tight feedback loop between the leading AI-first product and the AI platform to motivate the stack and its roadmap.
Jay Parikh will lead this group as EVP of CoreAI – Platform and Tools, with Eric Boyd, Jason Taylor, Julia Liuson, Tim Bozarth, and their respective teams reporting to Jay.
Jay will work closely with Scott, Rajesh, Charlie, Mustafa, and Kevin to optimize our entire tech stack for both performance and efficiency. Additionally, Jay and team will lead our progress and work around developer productivity and Engineering Thrive across the company.
As our cloud infrastructure business continues to grow and scale to become Microsoft’s largest business, Scott will continue to lead Cloud + AI to ensure we’re delivering the quality, security, and innovation that our customers and partners count on for their most mission-critical applications, databases, and AI workloads.
Ultimately, we must remember that our internal organizational boundaries are meaningless to both our customers and to our competitors. When we talk about operating as One Microsoft, we are effectively talking about how we are continually increasing our customer focus, raising the bar on our innovation, and driving accountability, so we can truly live up to our mission.
Our success in this next phase will be determined by having the best AI platform, tools, and infrastructure. We have a lot of work to do and a tremendous opportunity ahead, and together, I’m looking forward to building what comes next.
Satya

Reference frame for MATLAB-SimPowerSystems’ asynchronous machine model measurement signals (e.g phiqr,phidr)
I am trying to understand in which reference frame MATLAB-SimPowerSystems’ "Asynchronous Machine Model SI unit" calculates various measurements signal (e.g phiqs, phids) . I selected synchronous reference frame in the GUI of the model. But it seems measurement values are not in the synchronous reference frame. By synchronous reference frame I mean reference frame which is rotating at speed equals to the machine speed plus slip speed. It seems measurements signals are in the reference frame which rotates at fixed speed corresponding to the frquency input given in the GUI (Parametrs tab). When input supply frequency matches with the Parameter tab’s frequency then only I am getting perfect dc value of d axis rotor flux (phidr) and q axis rotor flux (phiqr) signals .If my understanding is correct then in steady state phidr and phiqr in synchronous reference frame should always be constant (dc) .

Use Arduino as controller (HIL) for a simulink modelled physical system
Hello Everyone,
I’ve been searching for an answer to this question and haven’t found anything quite applicable in past items from this forum. Would appreciate any guidance you all can give. I have modelled a system (inverted pendulum) in Simulink and tuned a PID controller for support. My next step is to convert my current continuous controller into a discreet form and write that in the Arduino programming environment then upload to the board. That part is not an issue. What I need help with is to replace the controller sub system I have in simulink with controls sent to/from the actual Arduino itself.
What I need to do is simulate the system in Simulink and send the various state information via USB to the Arduino for processing then read that information back in to update the simulated system. Is this possible and does anyone have ideas for where to start? I have already downloaded the Arduino support module but that seems more for laying out a full system to upload onto the Arduino board and run separate from the computer. (While a useful function, it’s not applicable to the project I want. I do want to program the controller separately using the standard c-based language for the arduino.)
Thank you in advance for any help!

Even though after adding existing .mat file. The signals exists in .mat file also not appeared in the signal editor. I think the side inputs panel was missing . Is there any way to get the side inputs panel ? please let me know the solutionHi,

How to make an FRF with my accelerometer Data and FFT?
Dear, Matlab Users.
I have some inquiries about my accelerometer Data, that was processed by a Dewesoft Software.
So, I am gonna share my code and data, and I would like to know if there any suggestion to this resolution.
Sensitivy: 102 mV/g, or 10.40 mV/m/s^2
%Load data
clear all
load("C:UsersjoantDesktopField_ResearchMatlab_Codedata_test.mat")
whos
close all
%Plot the array according to the data
%Data of Channel 1
g1= transpose(Data1_352C33OLD)
t1= transpose(Data1_time_352C33OLD); % time
dt=1/(Sample_rate) % period
L=length(g1)
%Iterate
% Figure of Channel 1
figure(1)
plot(t1,g1,’b.-‘)
set(gca,’Fontsize’,14)
xlabel(‘time(s)’)
ylabel(‘g’)
xlim([min(t1) max(t1)])
%ylim([-6 6])
grid on
% Calculate Fourier transform of force
points=round((t1(L))/dt) %Calculate the points
A_F= g1; % This is the Force for setting in the fft.
freq= (0:1/(dt*points):(1-1/(2*points))/dt)’; %Hz
freq=freq(1:round(points/2+1),:); %Hz
length(freq)
length(fft(A_F))
%In this part I need help
A_fft=fft(g1); %without the conversion by 9.8 m/s^2
abs_A=abs(A_fft)
figure(4)
plot(freq,abs_A(1:length(freq)))
xlim([0 6]) % Because 5 Hz is 300 RPM
%ylim([-400 400])
xlabel(‘Frequency (Hz)’)
ylabel(‘g’)
%According to the practice in the laboratory the result is the following
%image.
This was my process to obtain the FFT, I would like to know if this process is correct?. Because when I plot this data is not the same values in y-axis that I had in the Dewesoft software.
Dewesoft fft(g) (attached) vs matlab fft(g) (attached)
Question #2
According to a Mechanical vibration book, I have the next equation to find the FRF. I applied this but my FRF y axis value is too high so, I don’t know If I didn’t applied correctly. That information is in my code and I use the following equation.
w= natural frequency = 31.42 rad/s^2.
I assumpted that A/F is g because according to the book, it says the next information: "Because the acceloremeter produces a voltage that is proportional to acceleration, we obtain the accelerance, A/F(w), from the dynamic signal analyzer".
My graph result:
This graph it doesn’t have sense, because I need values aroun of 0.15-0.17 in the first vibration mode. So, I would like to know if there any suggestion how to resolve this.
Best Regards,
Jo98.Dear, Matlab Users.

Dewesoft fft(g) (attached) vs matlab fft(g) (attached)
Question #2
According to a Mechanical vibration book, I have the next equation to find the FRF. I applied this but my FRF y axis value is too high so, I don’t know If I didn’t applied correctly. That information is in my code and I use the following equation.
w= natural frequency = 31.42 rad/s^2.
I assumpted that A/F is g because according to the book, it says the next information: "Because the acceloremeter produces a voltage that is proportional to acceleration, we obtain the accelerance, A/F(w), from the dynamic signal analyzer".
My graph result:
This graph it doesn’t have sense, because I need values aroun of 0.15-0.17 in the first vibration mode. So, I would like to know if there any suggestion how to resolve this.
Best Regards,
Jo98. Dear, Matlab Users.
I have some inquiries about my accelerometer Data, that was processed by a Dewesoft Software.
So, I am gonna share my code and data, and I would like to know if there any suggestion to this resolution.

[Simulink Support Package for Arduino Hardware] CAN Recieve Block issue
Hello,
I am a student currently using the Simulink Support Package for Arduino Hardware to implement CAN communication.
The issue I am facing is that the CAN Receive block does not receive any data when messages are sent using an Extended ID. I am using an Arduino MKR WiFi 1010 along with the MKR CAN Shield. My Simulink model is used to send CAN messages to a motor and receive CAN messages from the motor.
The Simulink model (I attach the file.) I created, along with the configurations for the CAN Transmit and CAN Receive blocks, which are shown below. (The Fixed Step Size is set to 0.002.)
To verify the transmitted values, I used a ‘USB to CAN Analyzer’. (link: https://www.seeedstudio.com/USB-CAN-Analyzer-p-2888.html?srsltid=AfmBOooUz103F-Q3hiV6ocaQKvJwR2POvokjnFucYIHxf77tjr7DDkJe) As a result, I confirmed that messages with Extended IDs 0x302 (=770)and 0x2902 (10498) exist on the bus. (0x302: Arduino transmit, 0x2902 Arduino receive)
However, when checking the results from the To Workspace block, I found that no data is being received, unlike what I observed with the USB CAN Analyzer.
To rule out a hardware issue, I also tested with the MATLAB Support Package for Arduino Hardware, and it worked correctly. The MATLAB code (attached) successfully received messages.
clear arduinoMKRObj;
clear rxObj1;
%% MKR
arduinoMKRObj = arduino(‘COM18′,’MKR1010′,’Libraries’,’CAN’)
rxObj1 = canChannel(arduinoMKRObj, ‘MKR CAN Shield’,"BusSpeed", 1000e3)
runtime = 10; % time to read (s)
tic; % start reading
while toc < runtime
% read data
readMsg = read(rxObj1);
if ~isempty(readMsg)
disp(‘Data received:’);
disp(readMsg);
else
disp(‘No data received’);
end
end
What should I do next? Could this be a Simulink-related issue? Any help would be greatly appreciated.
