Abstract In order to avoid the adverse effect of rotor position detection error on permanent magnet synchronous motor (PMSM) speed control system and improve the reliability of the system, a model predictive power control method equivalent to the id=0 control method is proposed to improve the reliability of the system in this paper. Through the establishment of a motor incremental model in a two-phase stationary coordinate system, the enumeration method is used to predict the current under the action of the basic voltage vector, The sampled voltages and currents are used to estimate the back electromotive force and the instantaneous power on rotor side. Then, the cost function based on power are established to select the optimal voltage vector. The proposed method does not need to use a high-resolution position sensor to detect the rotor position angle for decoupling transformation of the rotating coordinate, which reduces the complexity of the system. The incremental model predicts currents without using permanent magnetic flux linkage parameters, which reduces the sensitivity of the algorithm to changes in the motor parameters. A comparative study between the proposed method and direct power control were conducted in terms of power ripples, torque ripples and dynamic response. The experimental results verify the effectiveness of the control method.
