摘　　要：选择了助力电机型号,建立了电机的数学模型。将基于混合灵敏度方法的H∞鲁棒控制理论应用于助力电机的控制策略研究,设计了H∞鲁棒控制器。经仿真验证,所设计的H∞鲁棒控制器不但使系统具有良好的瞬态和稳态性能,而且能有效地抑制噪声的干扰,增强了系统的鲁棒性和抗干扰能力。This paper selected the type of assisted motor, and established its mathematical model. The application of H∞ robust control theory based on mixed sensitivity method to the control strategy of assisted motor was studied. A H∞ robust controller was designed and simulated. The simulation result showed that the H∞ robust controller enabled the system to have the good transient state and stable state performance, and it can effectively restrain the noise interference, strengthen the robust performance of system.
