Research on Speed Control System of PMSM Based on Active Disturbance Rejection Control

摘要

Permanent magnet synchronous motor (PMSM) is widely used in aerospace, new energy electric vehicles and other fields. In order to solve the problems of poor parameter adaptability and poor disturbance resistance in the PMSM speed control system with traditional PI control algorithm, a linear active disturbance rejection control (LADRC) algorithm for PMSM is proposed in this paper. Then, the physical meaning of each parameter in LADRC and the setting scheme are summarized according to the phenomena encountered in the experimental. Simulation and experiment show that the proposed scheme can improve the robustness of PMSM speed control system.
