摘要
为了提高永磁同步电机控制系统的抗扰性能和控制精度,提出了一种改进自抗扰控制的永磁同步电机控制策略。首先,建立了永磁同步电机的动态数学模型。其次,在速度外环设计了一种串级线性-非线性的自抗扰控制器,该控制器结合了线性和非线性自抗扰控制的优势,前级采用线性自抗扰,后级采用非线性自抗扰,并引入带限幅的改进fal函数,使其能够有效提升控制系统的抗扰能力。最后,通过对基于PI控制、传统自抗扰控制和改进自抗扰控制的永磁同步电机控制系统的仿真对比,验证了该方法的有效性。
This paper proposes a permanent magnet synchronous motor control strategy with improved active disturbance rejection control.Firstly,a dynamic mathematical model of the permanent magnet synchronous motor is established.Secondly,a serial linear-nonlinear self-immunity controller is designed in the speed outer loop,which combines the advantages of linear and nonlinear active disturbance rejection control.This controller adopts linear ADRC in the front stage and nonlinear ADRC in the back stage,and introduces an improved fal function with limiting to enhance the immunity of the control system.In addition,an improved fal function with limiting is introduced to enhance the immunity of the control system.Finally,the effectiveness of the method of this paper is verified through the simulation comparison of the PMSM.
