Predictive torque control of a permanent magnet synchronous motor fed by a matrix converter without weighting factor
Finite control set model predictive control is a flexible control scheme with fast dynamic. The standard form of this controller is based on the minimization of a cost function. The cost function needs weighting factors that is dependent to the system parameters and operating point. The tuning of the weighting factors requires nontrivial process. This paper presents a predictive direct torque and stator flux control of a permanent magnet synchronous motor fed by a matrix converter without weighting factor. The proposed method uses a multiobjective optimization based on a ranking approach instead of a cost function. Therefore, the tuning of weighting factors is unnecessary. Simulation results are presented to confirm the good performance of the proposed method.
