摘要

A robust model-predictive direct-speed control based on full parameters and load observer (MP-DSC+FPLO) for the surface-mounted permanent-magnet synchronous motor (SPMSM) drives is proposed in this paper. Firstly, MP-DSC based on direct voltage-selection cost function is introduced. Then, a sliding-model full parameters and load observer (FPLO) that can simultaneously estimate electrical parameter, mechanical parameter, motor speed and load torque is proposed. Thus, the load torque observer in conventional MP-DSC method is eliminated. Finally the output of the proposed FPLO is used to compensate the predicted reference voltage. The simulation and experimental results show that the proposed method is robust to the disturbances of parameters and loads.
