基于滑模自抗扰的永磁同步电机控制系统设计
Design of PMSM Control System Based Sliding Mode Active Disturbance Rejection
摘要
Abstract
Sliding mode active disturbance rejection controller(ADRC)was presented and designed for controlling the permanent magnet synchronous motor(PMSM)servo system with parameter variation uncertain disturbance. Based on the mathematical model analysis of PMSM servo system,the internal uncertainty and external random disturbances caused by system parameter change were regarded as"total disturbance". The linear extended state observer was designed to observe and compensate the system,which was approximated to integrator series type. The closed-loop servo system was fast controlled by sliding mode state feedback,and its stability was proved by Lyapunov method. Compared with LADRC,the simulation shows that the capability of disturbance rejection and robustness of PMSM are improved by the presented siding mode ADRC strategy.关键词
