Tuning PI in a loop

Hello,

i have a simulink model with two PI-controllers and i want to tune them. The problem is, the automatic tunning doesnt work. I would like to tune them in a loop, with incementing the parameters. Have somebody experience with such things?

Hi Michael,

You can use the PID Tuner App and similar functions that are shipped with the Control System Toolbox for help with tuning a PID.

In addition you may find the following examples useful in getting started:

1) Tune PID Controller to Favor Reference Tracking or Disturbance Rejection

2) PID Controller Tuning in Simulink using Simulink Control Design

My problem is, that i have to account the the accelaration force, which appears during the start and stop process and is not linear, because it depends on the acceleration of the mass! So the load is also not linear!

With a constant load the vector control and the ac model works how they should do!
