PID Tune: Plant cannot be linearized
조회 수: 9(최근 30일)
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?

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.
