Analog PID controller to Discrete PID controller

hello, i have created an Analog time PID controller and i want to convert it onto a discrete time PID controller. can somebody tell me how to do it?

Thank you!

Answer 1

[Hyunuk Ha]

You can simply replace pid parts with built-in blk :

In Library Browser, discrete -> discrete PID blk.

[Nipun Loran]

thank you!, but is there any other way to use unit delays and zero hold, and create a Discrete PID witout using the block?

Analog PID Controller. Find TF of analog PID Controller and use command c2d in MATLAB.
