Predictive control has emerged as an attractive alternative for the control of matrix converters. The predictive control is a flexible method to control different variables through the minimization of a cost function. In drive system, the predictive control can be divided to predictive current control (PCC) and predictive torque control (PTC). In PCC, the stator current is evaluated in cost function, but in PTC the torque and stator flux are evaluated in the cost function. On the other hand, the ability of matrix converter in control of input source current can be easily included in both PCC and PTC. This paper introduces the methodology and the results of a comprehensive comparison of PCC and PTC techniques for a permanent-magnet synchronous motor (PMSM) fed by amatrix converter. The comparison involves the investigation of the torque and stator flux ripples, the total harmonic distortion of input and output currents, and the input filter resonance as figures of merit. Different performance indicators that present an instruction for the selection of predictive control methods for PMSM drive applications by matrix converters for engineering practices are provided with this comparative evaluation.
