Description: 首先，介绍了交流调速及其相关技术的发展现状和发展趋势，以及交流调速系统的主要控制策略。选用工业变频器用异步电机作为研究对象，利用坐标变换理论，分析了异步电机在三相静止坐标系、两相静止与旋转坐标下的电机基本数学模型及其矢量控制原理。利用转子磁场定向的矢量控制技术，实现了异步电机定子电流的转矩分量和励磁分量的解耦。分析了空间矢量脉宽调制算法以及实现方法，最后设计了异步电机的双闭环矢量控制系统。
然后，利用Matlab/Simulink搭建了异步电机数学模型，建立了基于电压空间矢量脉宽调制的异步电机矢量控制模型，包括电机模块、坐标变换模块、磁链观测模块、PI 调节模块、SVPWM 模块等，进行了电压电压空间矢量控制的仿真验证。-this paper introduced the current condition and future trend of AC speed-adjustmentSystem and its main control strategies, on the base of the asynchronous motor used in industrial frequency converter , the mathematical model under three-phase static coordinate system , two-phase static coordinate system and circular coordinate system and the principle of vector conttrol are analyzed by using the theory of coordinate transformation . Then the components between torque and magnetic field of stator winding currrent are decoupled which uses the rator-field-oriented technology.After space vector PWM modulation algorithms and implementation methods have been analyzed, dual closed-loop vector control system of asynchronous motor isworked out.
