| 摘 要： | 为了进一步提高永磁同步电机(permanent magnet synchronous motor, PMSM)无传感器控制的观测精度，提出了基于反步鲁棒控制与改进跟踪微分器的PMSM无传感器控制方法。首先，建立了PMSM的数学模型。其次，以Sigmoid函数为基础，设计跟踪微分器，实现对PMSM转子转速和位置的观测。然后，为了提高系统的抗扰能力，将反步控制和鲁棒控制相结合，对PMSM调速系统设计了反步鲁棒控制器。最后，设计了双曲正切跟踪微分器对外部负载进行实时观测，并将其补偿给控制系统，达到降低负载扰动对电机转速影响的目的。实验结果表明，该观测器对电机转子转速和位置具有良好的观测效果，同时反步鲁棒控制也具有较高的控制精度，对负载有很好的抑制效果。

| Abstract: | To improve the observation accuracy of sensorless control of a permanent magnet synchronous motor (PMSM), a sensorless control method based on backstep robust control and an improved tracking differentiator is proposed. First, the mathematical model of a PMSM is established. Second, based on the Sigmoid function, a tracking differentiator is designed to realize the observation of the speed and position of the PMSM rotor. Then, to improve the anti-interference ability of the system, the backstep and robust controls are combined, and the backstep robust controller is designed for the PMSM speed regulation system. Finally, a hyperbolic tangent tracking differentiator is designed to observe the external load in real time and to compensate the control system to reduce the influence of load disturbance on the motor speed. The results show that the observer has a good observation effect on the speed and position of the motor rotor, and the backstep robust control also has high control accuracy and a good inhibitory effect on the load. |
