PERFORMANCE IMPROVEMENT OF THREE PHASE INDUCTION MACHINE FED BY INDIRECT MATRIX CONVERTER USING PREDICTIVE CURRENT CONTROL

Abstract — A new strategy for indirect matrix converters which allows an optimal control of source and load currents of induction motor is presented. The commutation state of the converter in the subsequent sampling time according to an optimization algorithm given by a simple cost functional and the discrete system model. The control goals are regulation of output current according to an arbitrary reference and also a good tracking of the source current to its reference which is imposed to have a sinusoidal waveform with low distortion. The indirect matrix converter fed induction motor model is simulated in Matlab/Simulink platform and the results are analyze
