研究异步电动机的控制，针对异步电动机模型的不确定性问题，首先将其线性化，然后将H2/H∞控制器应用于异步电动机的调速系统中，将异步电动机调速系统的性能要求转化为混合H2/H∞控制器的设计问题。提出将基于H2/H∞控制器参数的设计方法运用到异步电动机控制系统中，很好地保证了负载等外部因素扰动情况下的系统鲁棒稳定性，保证闭环系统具有的动态和稳定性能，很好的保证了异步电动机对扰动的稳定性。

The asynchronous motor control is studied in this paper. Because of uncertainty, the model of the asynchronous motor is linearized first, and then the mixed H2/H∞controller is used in the asynchronous motor speed adjusting system, and the performance requirements of the induction motor speed adjusting system transforms into the design problem of the mixed H2/H∞controller. The design method based on the H2/H∞controller is applied in the induction motor control system, and ensure the system robust stability, dynamic stability of the closed loop system, and ensure the stability of the induction motor's speed under load disturbance and other factors.
