中文摘要
      针对一类时变不确定系统, 研究基于状态观测器的鲁棒重复控制系统设计问题. 通过状态观测器重构系统状态, 利用重构状态进行状态反馈. 基于2维系统稳定性理论, 应用线性矩阵不等式(LMI)方法, 推导出了重复控制系统存在状态观测器和重复控制器的一个LMI条, 并用LMI的可行解给出了状态观测器和重复控制器参数的具体形式. 最后用数值仿真验证了本文所提方法的有效性.
英文摘要
      The problem of designing a robust repetitive-control system is studied based on a state observer for a classof plants with structural time-varying uncertainties. The reconstructed states from the state observer are employed in the state-feedback controller design. Based on the stability theory of two-dimensional (2D) systems, a sufficient condition for the existence of the state observer and the repetitive controller for the repetitive control system are presented in terms of a linear matrix inequality (LMI) whose feasible solutions are utilized to determine the parameters of the state observer and the repetitive controller. A numerical example demonstrates the effectiveness of the method.
