Abstract

This paper investigates the use of a novel model-predictive control strategy to control an induction motor fed by a matrix converter. The proposed control method combines the features of classical Model Predictive Control and the Space Vector Modulation technique into a Modulated Model Predictive Control. This new solution maintains all the characteristics of Model Predictive Control (such as fast transient response, multi-objective control using only a single feedback loop, easy inclusion of nonlinearities and constraints of the system, the flexibility to include other system requirements within the controller) adding the advantages of operating at a fixed switching frequency and improving the quality of the controlled waveforms. Simulation results employing the control method to a direct matrix converter induction motor drive are presented.
