I have a set of linearized plants which are approximation of a nonlinear system at different operating points. I want to tune PD/PID controllers for each of these plants. I tried doing it for each plant separately using ga command. Is there any way to tune all the PID controllers for each of the plants simulatineously using ga command?

Hi @SM
For multiobjective optimization, then you should consider using this gamultiobj() command.

You can follow the examples in the documentation.
