Position Control Performance Improvement of DTC-SVM for an Induction Motor: Application to Photovoltaic Panel Position

Abstract

This paper deals with the adaptive sliding mode control DTC-SVM approach dedicated to the position control of photovoltaic
panels according to the maximum sunshine position to allow a high efficiency of photovoltaic systems. The paper is devoted to
the presentation of a comparison study between three DTC-SVM strategies applied to the position control of an induction motor:
(i) a DTC-SVM strategy using PI controllers, (ii) a DTC-SVM strategy using PI controllers with a nonlinear compensator, and
(iii) a DTC-SVM strategy using sliding mode controllers. Moreover, using estimations of machine parameters updated online, the
robustness with respect to parameter variations of the induction motor is also tested. These performances are confirmed by simulation
works.
