A new extended cascaded predictive control ECGPC of an induction motor drive with energy saving

Abstract

A new extended cascaded predictive control method ECGPC is synthesized under energy saving of the induction motor drive to improve high efficiency. The method gives the possibility to control at the same time different variables more than in conventional cascaded CGPC. For this method, the plant is assumed to be divided into three parts and three G.P.C. algorithms must be computed. The control law is then derived under polynomial structure in order to analyse the stability of the different controlled open loops in the frequency domain. Simulation results demonstrate the performance of the proposed method
