PMSMs are mainly controlled using DTC and FOC. However, these methods suffer from relatively high torque and stator flux ripples. This article suggests a model-predictive control strategy in which, exploiting stator flux observer and optimized cost function, the dynamic response of the motor is improved. The stator flux and y-axis current are considered as the state variables. Stator flux observer is exploited to estimate the flux and torque angles. Moreover, a cost function with optimized… Expand
