摘要：

针对永磁同步电机在一些工作场合精度要求较高的情况,在永磁同步电机数学模型的基础上,文中提出了一种二阶Super-Twisting滑膜理论算法。该方法对电机的反电动势观测值进行运算处理,通过得到电机速度和位置信息来实现永磁同步电机无位置传感器控制。根据Lyapunov稳定性理论可知,该控制系统稳定。在MATLAB/Simulink工具中搭建系统仿真模型来验证该理论算法的有效性。仿真结果表明,相较于传统滑膜观测器,该算法有效削弱了滑膜抖振,提高了系统的估算精度和响应速度,使其能更好地跟踪转子的位置和速度信息。

Abstract:

In view of the high precision requirement of permanent magnet synchronous motor in some workplaces, an algorithm based on second-order Super-Twisting synovium theory is proposed based on the mathematical model of permanent magnet synchronous motor. In this method, the motor speed and position information are obtained by calculating the observed value of the back electromotive force of the motor, so as to realize the sensorless control of the permanent magnet synchronous motor. According to Lyapunov stability theory, the observer converges. MATLAB/Simulink is used to build a simulation model of the control system to verify the feasibility of the control system. The simulation results show that compared with the traditional synovial film observer, the proposed algorithm can effectively reduce the chattering of synovial film, improve the estimation accuracy and response speed of the system, and enables it to track the rotor position and velocity information better.

Key words: Super-Twisting algorithm, permanent magnet synchronous motor, sliding observer, Lyapunov stablility, position sensorless control, vector control, sliding mode theory, observe the rotational speed
