Why do the same system matlab and simulink get different step responses?
As I asked, I want to design a fractional pid controller for a model. Unfortunately, the results I got with step in matlab are quite different from those in simulink
.
Here the orange line is the output and the blue line is the offset,Now let me show you the situation of matlab.The specific parameters of the controller are consistent with the code below
cs=fopid(9.503084707494814e+03,1.889631254823942e+02,2.304958553299564e+02,0.058440555124293,1.558103446462550);%This is parameter of controller
gs=tf(118700,[1 1085 1224000]);%This is the transfer function of the controlled object
step(feedback(cs*gs,1))%Step Response of Closed-loop Transfer Function
This is the general situation. I feel confused now.As I asked, I want to design a fractional pid controller for a model. Unfortunately, the results I got with step in matlab are quite different from those in simulink

Network Protection Set to Block Mode, but Clients Showing Audit Mode – Possible GPO Conflict?
Hi everyone,
I’ve run into an issue where I’ve created an Intune policy to enable Network Protection in block mode. However, when I check locally on the clients, I see that the policy is configured in audit mode instead of block mode.
I’ve verified in Intune that the devices have successfully synced and received the policy. During my troubleshooting, I found that some GPOs can take precedence over Intune policies.
Could this be the reason why the Network Protection is only set to audit mode on the clients? Has anyone else experienced this issue or have any insights?
Thanks in advance for your help!

Is there a way to model sound wave interference patterns using Phased Array System Toolbox?
I am trying to find a way to model the constructive/destructive interference patterns for sound speakers in a room, i.e. concentrating sound in a specific part of the room through creating constructive interference from several non-directional (aka regular) speakers. I have been looking at the Phased Array System Toolbox (because I am thinking about an array of speakers) and think that might be the best fit for what I am looking for. Not sure if there is another Toolbox out there that does similar things or the Phased Array System is the best fit for this?

Troubleshooting Bootmgfw.efi Problems Preventing Windows 10 Booting
Salutations!
I have been enjoying the experience of simultaneously running Linux Mint and macOS on my laptop by utilizing separate external SSD drives for each operating system. The boot loader I’ve been employing is rEFInd. Recently, however, I encountered an issue when attempting to boot into macOS. A message appeared on the screen stating:
“Error: premature end of file /EFI/APPLE/BOOT/BOOTX64.efi.”
Despite my efforts to resolve this problem through online research, I could not find any useful resources addressing this specific premature end error. The solutions provided were more geared towards cases where the mentioned file was missing altogether.
To address the issue, I attempted to use the macOS recovery system. However, upon opening the Disk Utility, the external SSD drive housing macOS was not detected. Only the USB drive containing the macOS installer was visible.
Feeling quite uncertain about how to proceed, any guidance or assistance would be greatly appreciated.

Unusual Problem with Boots
Thank you for taking the time to engage in this content.
I am a user of Windows 10 Home edition and I typically keep my computer running continuously. Recently, I encountered a major issue when my PC forced an update that caused it to fail to boot back into the operating system. Despite trying various troubleshooting methods like entering automatic repair and utilizing commands like bcd and diskpart, I was unable to regain access to Windows.
After spending considerable time attempting to resolve the issue and consulting online resources, my system reached a point where it no longer recognized the drives as boot drives. I even encountered corruption in my USB drive when attempting to use it as a workaround for accessing Windows. Reinstalling Windows using the recovery tool proved unsuccessful, and it seemed as though the operating system was present but inaccessible.
In a moment of desperation, I removed the hard drive from another computer also running Windows 10 and managed to successfully boot my system from it. While this allowed me to access Windows and confirm that all my drives were functional, I am now faced with the challenge of restoring my system to boot from the solid-state drive that has been its primary boot drive for years.
Can you suggest any solutions to help me restore the original boot functionality to my solid-state drive?

How to Cut, Copy, and Paste in Windows 11
I asked about this previously, but unfortunately lost the link. I recently upgraded my computer operating system to Windows 11, and I’ve noticed that I now have to tap on “Show More Options” every time I copy and paste. This was one of the reasons why I hesitated to upgrade to Windows 11 for so long. However, I finally decided to upgrade because I was tired of constantly receiving upgrade notifications.
Now that I’m on Windows 23H2, if anyone has a solution to this issue, please kindly share it with me. It’s frustrating to have to go through an additional step for something as simple as copying and pasting, especially since I use this function daily. Thank you in advance for your help.

Struggling with Freezes After Fresh Installation of Windows 10
This is a completely new setup, the third attempt, and while it functions smoothly once running, it is marred by the necessity of 4-5 hard resets every day (within just 4 days). The recurrent need for resets seems entirely random and frustrating.
Launching a program requires a delay of 15-30 seconds after double-clicking – if the program even starts. Often, multiple clicks are needed due to a slightly unresponsive mouse. The tower has been reset so frequently that a crucial 40GB ORP file intended for archiving, acquired legally through torrenting, has now rendered the storage drive unusable. Until this issue is resolved or I revert to Windows 7, the drive remains disconnected.
For instance, when I installed Wordweb, a popup dictionary, and attempted to launch it, the system froze completely. After utilizing the reset button (my trusty companion), the program ran smoothly, but my Firefox profile suffered irreparable damage.
The main suspect in this situation is ZoneAlarm, an older version that has operated without issue or complaint. Apart from small applications like Total Commander and MusicBee, nothing else has been added to the system.
