摘　　要：研究异步电机控制系统优化问题,系统要求稳定性和抗干扰性能。传统的矢量控制中速度调节器和电流调节器采用PI调节器,依据PI调节器特性,在控制过程中速度响应会出现超调。为了解决上述问题,提出了一种异步电机矢量控制中速度调节器的设计方法,以抑止异步电机矢量控制中速度响应的超调和增强抗扰性为目的。异步电机矢量控制采用转子磁场定向实现解耦,并采用速度环、电流环双环控制方法,根据内模控制原理,设计用一种速度调节器,取代常规的PI调节,成功解决了转速的超调和负载扰动对电机转速的影响。仿真结果表明,提高了响应特性,为优化设计提供了参考。Studying the problem of induction motor control system optimization. The system requires stability and robustness. The speed regulator and the current regulator of traditional vector control use P1 controller, and the speed responses often overshoot in the control process. In order to solve these problems, we proposed a design method of speed controller in the induction motor vector control for the purpose of suppressing speed response overshoot in induction motor vector control and enhancing immunity. The induction motor used field oriented vector control to achieve decoupling, and used double loop control method of the speed loop and the current loop. According to the principle of internal model control, we designed a speed regulator to replace the conventional PI regulator, which successfully resoluted the effects of speed overshoot and load disturbance on the motor speed. Simulation results show that the method can improve response characteristics and is the reference to the design of optimize.
