摘要
针对基于高频脉振注入法的PMSM无位置传感控制系统在启动或低速调速时,转速响应的快速性和无超调性不可兼得的问题,设计了一种基于改进型自抗扰控制策略的速度控制器,该控制器采用一阶自抗扰结构来减少控制参数,同时采用fhan函数作为过渡函数,使转速响应具有较好的适应性,并给出控制参数的整定方法,有效地改善了基于高频脉振注入法的PMSM无感系统的控制效果。通过建立Simulink仿真模型和硬件实验平台,对比基于改进型自抗扰控制与基于传统PI控制的PMSM无感控制系统的调速响应,结果表明采用改进型自抗扰的速度环控制器在无感控制系统启动与调速过程中,能够有效解决快速性和无超调性之间的矛盾,实现对电机的良好控制。
Aiming at the problem that the rapidity of the speed response and the non-overshoot cannot be achieved in the PMSM posi-tionless sensor control system based on the high-frequency pulse injection method when starting or adjusting the speed at a low speed,a speed controller based on improved active disturbance rejection method is designed.The speed controller of the control strategy adopts the first-order active disturbance rejection structure to reduce the control parameters.At the same time it uses the fhan function as the transition function,so that the speed response has better adaptability.The tuning method of the control parameters is given,which is ef-fective The control effect of the PMSM non-inductive system based on the high-frequency pulse injection method is greatly improved.By establishing Simulink simulation model and hardware experimental platform,the speed control response of PMSM non-inductive control system based on improved ADRC and traditional PI control are compared.The results show that when the improved ADRC speed loop control is adopted,in the process of starting and speed regulating of the non-inductive control system,the controller can effectively solve the contradiction between rapidity and no overshoot,and realize good control of the motor.
