Feedback-signal prediction for a deadbeat PI controller

Abstract

This paper considers an algorithm of feedback-signal prediction for implementing a current loop with a PI controller tuned for deadbeat control. The algorithm takes into account errors of incorrectly set inductance and the presence of a filter in the feedback signal. An algorithm for correcting the inductance of the control-object model and the proportional coefficient of the current PI controller is implemented. The final algorithm was tested taking into account measuring-channel discreteness.
