| 摘 要： | 针对简化的感应电机模型，文章提出了一种新的调速控制方法。根据给定的速度和磁链幅值，得到所需的磁链两相分量的参考值。然后对磁链的误差动态方程构造Lyapunov函数，从而设计电机电流的控制律使磁链误差收敛于零。这种控制方法非常简单、实用。仿真结果表明了此法的可行性，及其对电机电阻变化的强鲁棒性。

| Abstract: | A new control method is presented in this paper based on simplified induction motor model. The desired reference values of two-phase flux components are obtained firstly according to the given speed and flux magnitued. Then with the Lyapunov function of flux error dynamic equation between the referential and actual flux value,the control law of the motor current is developed to make sure the convergence of error. This method is very simple with the high robustness of the motor parameters uncertainty. The simulation results illustrate the performance. |
