永磁同步电机非线性黄金分割自适应转速控制

Nonlinear golden-section adaptive speed control of permanent magnet synchronous motor

针对永磁同步电机系统复杂设计高精确度的控制器比较困难的问题,采用id=0的矢量控制策略,基于永磁同步电机的特征模型,设计一个以非线性黄金分割自适应控制为主的控制方案。通过安排过渡过程和特征模型参数的在线辨识实现了该控制方案下控制器参数的在线自适应调节。实验结果表明该控制方案不仅能够实现永磁同步电机较高精确度的转速控制,与一阶自抗扰控制、增广状态反馈控制和传统的PI控制相比,具有更加优越的暂态和稳态性能。

Aiming at the complex system of permanent magnet synchronous motor（ PMSM）, it is relatively difficult to design a controller with high accuracy. Therefore, a predominantly nonlinear golden-section a- daptive control scheme is designed by using the id = 0 control strategy based on the characteristic model for the PMSM. The controller parameters on-line adaptive control was realized with the control scheme by arranging the transition process and characteristics of model parameter online identification. The proposed scheme can be implemented for the high precision speed control of permanent magnet synchronous motor through. Experimental results are given to illustrate that permanent magnet synchronous motor with the proposed scheme has more superior transient and steady-state performance compared with the first order active disturbance rejection control, the augmented state feedback control and traditional PI control.
