A Predictive Control Method for Improving the Robustness of Permanent Magnet Synchronous Motor

Abstract— The high-performance permanent magnet synchronous motor control system requires higher performance such as speed tracking ability and current response speed. To this end, this paper proposes a predictive control method for improving the robustness of permanent magnet synchronous motor. The outer loop adopts closed-loop rolling optimized rotational speed predictive control to improve the speed tracking capability. For the irreversible delay of one beat of the digital control system, the inner loop adopts Newton interpolation compensation deadbeat current predictive control enables the system to have stronger dynamic response capability. Then a reduced-order load observer is designed to improve the disturbance immunity of the system under load changes. Finally, the feasibility of the proposed control method is verified by simulation, and the steady-state accuracy and robustness of the proposed control method are higher than that of the traditional deadbeat current predictive control method.

Index Terms— PMSM; double closed-loop predictive control; rolling optimization; Newton interpolation compensation; deadbeat current predictive control.
