PID Tune: Plant cannot be linearized
显示 更早的评论
I am designing a grid connected PV system with battery and supercapacitor. In that model I am using three PID controllers inorder to control I battery and supercapacitor, but when I wan to tune these PID controlers it gives an error (PID Tune: Plant cannot be linearized).
Could you suggest any methods to tune these controllers?

Hi @Arash
Most likely your PV system has components that contain discontinuities. Thus, the Plant cannot be linearized.
However, you can identify/estimate the system model from the input–output data and then use that model for PID tuning purposes. Perhaps, learing from this tutorial is more effective.
