摘　　要：在分析感应电机数学模型的基础上,针对感应电机矢量控制系统的速度环、磁链环、电流环对误差响应的不同要求分别设计了三种控制器。其中速度环控制器的设计目标是增强系统稳态性能,以及对负载扰动的鲁棒性。磁链环设计思路是最大程度增强被控量的响应速度。以上两者分别采用滑模线不同的滑模控制器。电流环采用PI控制器加前馈解耦的设计,能增强电流环本身的动态响应,并且能有效加快速度响应。仿真表明,三种设计思路能够在同一矢量控制系统中实现稳定工作,并且各自达到了设计目标。Based on the theoretical analysis of mathematical model for induction motor, for the different require to the error response on the velocity loop, flux loop and current loop of the system,three controller was designed. The design purpose of the controller of velocity loop was to enhance the steady response and the robustness of load disturbance. The design purpose of the controller of flux loop was to enhance the response speed. These two controllers was designed based on the slide mode control theory. The current controller based on PI controller theory and decouple theory have the ability to strengthen the response of each current loop and velocity loop. The simulink results demonstrated that the controllers have well performance on one vector control system, and the design goals of three controllers were reached.
