中文摘要
      给出一种基于H∞控制理论的二自由度内模控制器设计方法.考虑了标称模型与实际模型之间存在乘性摄动时的失配性,利用适当的状态变换,将跟踪问题的控制器设计转化成一个调节问题的标准H∞控制器设计问题,再利用H∞输出动态反馈完成了控制器设计.以电力系统模型为例设计了一个二自由度H∞励磁控制器,仿真结果表明了此控制器的有效性.
英文摘要
      A two-degree-of-freedom(2-DOF)internal model controller (IMC) is synthesized based on H-infinity control theory. The multiplicative perturbation between nominal model and real model is considered. By suitably changing state, the controller design of tracking problem is turned into that of regulating problem. Then by using H-infinity dynamic output feedback, the design procedure of the controller is finally completed. A 2-DOF H-infinity excitation controller of a power system is designed. Simulation is given to illustrate the validity of the controller.
