Hi,
I am a new user to Simulink. I created a model and added a PID controller. When I tune the controller it says the response should be about 1 second with a 20% overshoot. When I run the model the reality is 1000 seconds with 10,000% overshoot. What could cause this to happen?
I created my own PID controller and modified the coefficients and it seems to be working, but I would definitely like to get the built-in PID controller working since I am spending about 5 hours just to tune my homemade controller.
I have been debugging for about a week now, I am not sure what look for. Any assistance would be greatly appreciated.
Thank you,
Alan
