Predictive control of an induction machine drive system for field-weakening regime

Abstract

In this paper is studied the model predictive control (MPC) of an induction machine (IM) drive for wakening applications. The control structure is implemented in Matlab software. The predictive control law is based on finite set combinations imposed by the two-level inverter topology. The study developed for field-wakening regime shows that the speed tracking objective remains stable despite stator resistance variation. Also, the load torque disturbance rejection is efficiently done to evaluate un unrated parameter. Thus, the operation of the IM drive with MPC law is robust on the sensitivity of parameters of the model.
