摘要：

针对基于空间矢量脉宽调制技术(SVPWM)和转子磁场定向控制原理的感应电机矢量控制系统,利用控制功能模块化的设计思想,在Matlab/Simulink中建立功能独立的子模块如矢量控制模块、速度控制模块、坐标变换模块、SVPWM子模块等,并将这些功能模块拼装组合,构建了电流、转速双闭环感应电机矢量控制仿真模型。仿真结果表明基于模块化设计的感应电机矢量控制仿真模型是有效可行的,为电机控制器的设计提供了一种途径。

Abstract: With the thought of modularized different functions of control system, the independent functional blocks such as vector control block, speed control block, coordinate transformation block and SVPWM block and so on were modularized based on the software of Matlab/Simulink. According to the vector control system of induction motors based on rotor field oriented and the space-vector pulse width modulation (SVPWM), the simulation model of vector control system for induction motors, which contains the speed loop and the current loop, was built through organically combining different functional blocks. The simulation results proved its reasonability and validity and it provided a new way to design motor controllers.
