本文运用时域地方法来处理感应电机控制中的干扰抑制问题．首先运用微分几何方法将非线性对象反馈线性化；然后采用本文提出的H∞干扰抑制方法达到预定的鲁棒性能指标和闭环系统的稳定．该方法只需求解一个代数Riccati不等式，避免了以往自适应方法计算的复杂性，仿真研究证实了该方法的实用性和有效性．
In this paper, the time domain method is used to deal with the problem of interference suppression in induction motor control. Firstly, nonlinear geometric feedback is linearized by using the differential geometry method. Then, the proposed H∞ interference suppression method is used to achieve the predetermined robust performance and stability of the closed-loop system. The method only needs to solve an algebraic Riccati inequality, which avoids the complexity of the previous adaptive method. Simulation results show the practicability and effectiveness of the method.
