摘要：永磁同步电机因其固有特性得到广泛应用，但由于永磁同步电机的非线性特性，针对该系统的控制器设计难度较大。本文建立了一种采用雅克比矩阵线性化永磁同步电机模型的反馈控制器，并使用非线性干扰观测器进行自适应更新。该方法替代了传统矢量控制中使用的3个PID控制器，对负载力矩扰动有很好的补偿作用,增强了电机控制的稳定性和鲁棒性，并通过Matlab/Simulink仿真结果进行了验证。

Abstract: Permanent magnet synchronous motor is widely used because of its inherent characteristics．But the controller design of PMSM system is difficult due to the nonlinear characteristics．This paper established a feedback controller using Jacobian matrix to linearize PMSM model，which updated adaptively with a nonlinear disturbance observer．Replaced the three traditional PID controllers used in vector control，and obtained a good compensation of disturbances of load torque．This method enhances stability and robustness of motor control．Results were verified with Matlab/Simulink simulation．
Key words: PMSM；vector control；feedback controller；disturbance observer；speed control
