The simulation failure could be caused by the derivative term of the discrete PID. More specifically, the derivative filter parameter N should be changed after discretization. If I use a continous PID with Kd=0 and change it to a discrete PID with Kd=0 too, there is no failure.

I think the model didn't work because you are mixing discrete and continuous signals in the summation block. The plant output should be sampled according to the controller sampling time.

Followed all the steps but when it comes to this video, it failed

Hope all of you are doing well...
I have analog signal and I want to convert into such data type for which I can develop logic.
In logic I want to use 0-100 like 60, 70, 25 or whatever I want.
How is it possible?

It is so hard to add a line to the Dashboard! The last step I tried no matter what but I could not succeed!

can you give me the link of simulink model which was made by you in above video?

How we can add scope in simulink screen itself as you have on right side?
