摘　　要：提出一个基于相似反对称结构设计的L2增益干扰抑制控制器.针对感应电机负载转矩的不确定性,在设计控制器时引入与不确定性参数相应的可调参数.以相似反对称结构为闭环期望结构,采用逆推法设计电机转速和转子磁链跟踪控制器.并通过L2增益算法进行耗散性分析,使系统不仅对不确定项具有鲁棒性,而且对外部干扰具有抑制作用,保证闭环系统的动静态品质.仿真结果表明了所提出控制器的有效性.Based on the design of similar skew-symmetric structure, a L2-gain controller was presented for interference rejection. Aimed at the uncertainty of motor load torque in the process of controller de- sign, some adjustable parameters corresponding to the uncertainty were introduced. Taking similar skew- symmetric structure as the desired closed-loop structure, a controller for motor speed and magneto-chain tracking was designed with inverse-inference method. The L2-gain algorithm was adopted to perform dissi- pation analysis, allowing the system to be not only robust in connection with the uncertain terms, but also restrains external disturbance, so that the static and dynamic performance of closed-loop system would be guaranteed. Simulation result demonstrated that proposed controller was valid.
