PID Controller

arturo.chunga.saavedra Nov 20, 2016 10:29 PM

Hi everyone,

I'd like to make a PID controller but I don't have any idea how to put it in program. Does anyone has any code example so I can guide myself? Actually I know the concepts off continuous process (laplace state) and I can discretize the function. But I don't know to put into codes.

Thanks in advance.
