摘　　要：为解决 ２自由度调节器具有参数不宜整定的缺点，针对感应电机调速系统，提出了一种新的２自由度调节器。其中，使用 Ｈ∞鲁棒控制理论设计抗扰调节器，在保证闭环系统稳定的前提下，抑制模型摄动及外扰对系统性能的影响。针对被控对象的标称模型使用 Ｐ Ｉ调节器做为跟随调节器，其优点是，两个调节器的设计均有明确的理论指导，调节器参数易于确定。Good servo performance and strong disturbance reject performance are two basic requirements about the speed regulation system of induction motors. But it is very difficult to adjust the parameters of a 2 freedom degree controller in order to meet the required performance. In this paper a new kind of 2 freedom degree controller with a new construction was proposed and used in the system of induction motors. It is easy to adjust the controller's parameters for the two adjusters involved in the controller. Using H ∞ control theory using to design the disturbance reject adjuster . The result of simulation experiment shows that the design is satisfied.
