摘要: 针对传统的自抗扰控制方法存在参数整定和响应速度问题,提出了一种新型的滑模自抗扰控制结构,构成了无速度传感器永磁同步电机滑模自抗扰调速系统。利用非线性干扰观测器(NDOB)取代扩张状态观测器(ESO)的综合扰动估计项,将滑模控制引入到非线性状态误差反馈控制律中,设计了滑模自抗扰电流控制器和速度控制器,利用李雅普诺夫理论证明稳定性。将电流控制器中的NESO观测值进行计算,得到电机的转子位置和转速估计值,构成无速度传感器的永磁同步电机调速系统。仿真结果表明了该方法的有效性。

Abstract: Aiming at the problem of parameter setting and response speed of the traditional ADRC method, a kind of novel sliding mode auto disturbance rejection speed controller is designed, and a sliding mode adaptive speed control system of PMSM without speed sensor is established. The nonlinear disturbance observer (NDOB) is used to replace the extended state observer (ESO) integrated disturbance estimation. The sliding mode control is introduced in the nonlinear state error feedback control; the sliding mode ADRC current controller and speed controller are designed; and the stability is proved by using Lyapunov theory. The rotor position and speed of the motor are estimated by the NESO measurement; and a system of PMSM without speed sensor is established. The simulation results show the effectiveness of the method.

Key words: permanent magnet synchronous motor, SM-ADRC, nonlinear disturbance observer, speed sensorless
