摘　　要：提出一个存在未知干扰的感应电机自适应抑制控制器.以相似反对称结构作为闭环期望结构,采用逆推方法设计电机转速和转子磁链跟踪控制器.通过分析闭环系统动态性能与控制器参数的关系,给出闭环响应速度的参数化调节方法.并利用外部干扰的线性参数化形式,提高转速和磁链的跟踪精度.仿真结果表明了所提出的自适应控制器的有效性.An adaptive restricting controller was presented for induction motor with unknown disturbance.Taking the similar skew-symmetric structure as a desired structure of the closed loop system,the tracking controller of motor speed and rotor magnetic linkage was designed with inversive inference.By means of analyzing the relationship of the dynamic performance of the closed-loop system to the controller parameters,a parametrizational regulation method for closed-loop response speed was given.The tracking precision of motor speed and rotor linkage was enhanced by employing the linear parameterized form of the external disturbance.The effectiveness of the proposed tracking controller was justified by simulation results.
