基于 SIMULINK 异步电机矢量控制系统分析摘要: 介绍了一种基于 SVPWM 的异步电机矢量控制系统。利用对转速、磁链双闭环的矢量控制,通过电压空间矢量调制的方式,对电机转矩直接进行解耦,从而达到理想状态下的控制性能。通过仿真的实验可知,该方法不但计算方便简单,容易实现,而且鲁棒性强,具有一定的现实意义。在异步电动机创建数学模型的前提下,叙述矢量控制等相关常识。把异步电动机三相静止坐标系下的不同变量转移到两相旋转坐标系中,之后通过转子磁场定向科技,促使定子绕组电流磁场与转矩分量得以解耦,最终,此类电机的调速效能显著提升,为创建SVPWM 矢量控制系统奠定良好基础。 继而对实验实施仿真与模拟,可以让人比较直观的观察此类控制系统,最终促使有关人员充分了解怎样才是此类电机的矢量控制。关键词:SVPWM;异步电机;矢量控制IAbstractAbstract : A vector control system of asynchronous motor based on SVPWM is introduced. The vector control of double closed loop speed and magnetic chain is used to decouple the torque of the motor directly. The ideal control performance is achieved through the mode of voltage space vector modulation. The simulation results show that the method is simple, easy to implement, and robust, and has certain practical significance.Based on the mathematical model of asynchronous motor, vector control theory and other basic knowledge are introduced. The rotor magnetic field orientation technology is used to decouple the current magnetic field component and torque component of the stator winding, thus the speed control performance of the asynchronous motor is greatly improved.Using SIMULINK to simulate and simulate the experiment, it can make people observe the vector control system of asynchronous motor more intuitively, so that people know exactly what is the vector control of asynchronous motor.Keywords :SVPWM;Asynchronous motor;vector controlII目 录第 1 章.引言.........................................................11...
