摘要
针对永磁同步电动机(PMSM)的特点,选用鲁棒性好、控制算法简单、易于工程实现的滑模观测器方法对电动机转子位置和速度进行估计。结合PMSM的数学模型与矢量控制理论,建立基于MATLAB/Simulink的无传感器PMSM矢量控制系统的仿真模型,并进行系统性能仿真分析,仿真结果验证了基于滑模观测器的无传感器控制方法的正确性与可行性。
According to the characteristics of permanent magnet synchronous motor,this paper choose a method based on SMO to estimate the rotor position and speed,which has a strong robustness,simple control algorithm and easy implementation of engineering application.With PMSM mathematical model and vector control theory,the sensorless PMSM vector control system simulation model based on MATLAB/Simulink is established,and system performance is analyzed,the simulation result verify the correctness and Feasibility of the method of sensorless control based on SMO.
