摘要

提出了一种异步电动机驱动的滑模控制方法。该方法基于异步电动机在机架中与定子电流矢量同步旋转的模型，具有两分量转矩解耦控制的特点;对电机参数变化不敏感。控制律用不等式而不是等式来表示。因此，当电机参数发生变化时，只要相应的不等式成立，就不会破坏滑模的稳定性和独立控制的特性。这就是为什么所提出的方法具有很强的鲁棒性。实验结果表明，即使在很大程度上改变电机参数，控制系统的性能几乎保持不变。

A novel sliding mode control method for induction motor drives

A sliding mode control method for induction motor drives is presented. Based on the model of the induction motor in the frame rotating synchronously with the stator current vector, the method possess two distinct features: decoupling control of the two components of torque; and insensitivity to motor parameter variations. The control law is represented in inequalities instead of equalities. Therefore, when the motor parameters are changed, the stability of the sliding mode and the feature of independent control will not be destroyed as long as the corresponding inequalities hold valid. That is why the proposed method is very robust. Experimental results show that even when the motor parameters are changed to a large extent, the performance of the control system remains almost unchanged.<>
