| 摘 要： | 异步电机矢量控制是在交流电机的双轴理论、机电能量转换和坐标变换理论的基础上发展起来的。为了实现对异步电动机磁场和转矩的解耦控制的目的;采用交流电机的磁场定向控制(即矢量控制)的方法;建立了一种在转子坐标系下异步电机的矢量控制系统仿真模型;仿真结果表明,基于矢量控制的方法能够实现对异步电机的解耦,即通过控制励磁电流分量和转矩电流分量的大小直接控制异步电机磁场和转矩,使交流异步电机获得和直流电机相媲美的控制性能。

| Abstract: | Asynchronous motor vector control technology is developed from the two-axis theory,electromechanical energy conversion and coordinate transformation theory of alternative current motor.In order to realize the decoupling control of asynchronous motor,a kind of asynchronous motor rotor coordinate vector control system simulation model was set up based on the principle of magnetic field directional control.The theoretical analysis and computer simulation results show that the method based on vector control can realize the decoupling of asynchronous motor.That is,through controlling exciter current component and torque current component to control the asynchronous motor magnetic field and torque,makes the control performance of AC induction motor can be comparable to the DC motor. |
