Abstract
Active-disturbance-rejection-control (ADRC) is a kind of control method which can obtain good dynamic and static performances. In order to effectively solve the problem of parameter tuning in ADRC in permanent magnet synchronous motor (PMSM) speed control system and maintain performance, an analysis of motor speed control principle have been made. Based on linear-active-disturbance-rejection-control (LADRC), a parameter tuning method of reference value filtered two-degree-of-freedom (2-DoF) control is proposed for LADRC current controller in speed control PMSM bypass changing and optimizing the structure of controller. The simulation and experimental results show that the stability and rapidity of the system are maintained and the parameters could be optimized by decoupling of system performance, and the correctness of the method for PMSM speed control is verified.
