PID Control in Python

A Proportional Integral Derivative (PID) controller is designed for a highly nonlinear system (chemical reactor). The steps are to (1) perform a step test, (2) fit a dynamic model, (3) obtain initial PID tuning parameters, (4) implement the controller, and (5) tune the controller. See apmonitor.com/do/index.php/Mai... for source files.

I've had problems with my PID integrator in the simulation project i'm doing until I saw this video, thanks a lot!

Glad it helped!

Thanks, really helpful.

Great Job I am looking for a controller with 2 temp inputs So I can control a pump. I want to have pump running when temp 1 is 10F higher than temp 2. any Ideas how to do that? thanks

[@daveball4707]

you could use an Arduino to do that using two temperature sensors

Great informative video sir.

Do you have any notes on how to simulate a gain scheduled PID controller on python?

[@apm]

The controller gain changes based on the PV. Here is a case study with PID and MPC: apmonitor.com/do/index.php/Main/NonlinearControl

I'm glad you liked the course content. Check out apm.byu.edu for additional courses.

Sir, is it possible to make PID with heating and cooling simultaneously.

[@apm]

A PID controller has only 1 manipulated variable. You could let the output be positive or negative and then turn on heating (+) or cooling (-) when the controller switches signs.
