摘　　要：介绍助力电机的应用,建立电机的数学模型。将H2最优控制理论应用于助力电机的控制策略研究,设计H2最优控制器。经仿真验证,所设计的H2最优控制器不但使系统具有良好的瞬态和稳态性能,而且具有较好的抗干扰能力,能有效地抑制噪声的干扰,增强系统的鲁棒性能。The application of assisted motor is introduced and its mathematical model is established. The application of H2 optimal control theory to the control strategy of assisted motor is studied. A H2 optimal controller is designed and simulated. The simulation result showed that the H2 optimal controller enables the system to have the good transient state and the stable state performance, moreover has better resistance to disturbance. It can effectively curb the noise interference, strengthen the system robust performance.
