I'm in my 3rd year of my electrical eng. degree. I have a project right now, where I must create a PID controller for implementation. They gave me the exact values for constants Kp, Ki, Kd and the maximum acceptable frequency.
My integrator circuit is based on the Miller integrator, but with a resistance in parallel with the capacitor, so I can have constant gain with low frequency signals.
My question is: How do I choose or calculate the values of the resistances and the capacitor, based on the max frequency they give me and the integration constant Ki?
My integrator looks like this picture:
I uploaded a photo of the PID i am trying to use. Feel free to point any erros. It uses a proporcional, integral and differentiator components and then a inverting summing op amp.
