中文摘要
      本文研究具有结构不确定性系统的鲁棒H∞状态反馈控制问题, 这个问题的解涉及到一个代数Riccati方程. 通过分析, 这个问题的解与一个辅助的线性时不变系统的H∞状态反馈控制问题的解是等价的, 把这一结果用于求解具有结构不确定性系统的鲁棒H∞动态输出反馈控制问题, 很方便地给出只需求解两个代数Riccati方程的鲁棒H∞动态输出反馈控制问题的解.
英文摘要
      This paper investigates robust H∞ state feedback control problem for the systems with struc- tured uncertainty. The solution to this problem involves one algebraic Riccati equation. Through analysis it is shown that the solution to this problem is equivalent to the solution to H∞ state feedback control problem for auxiliary linear time-invariant systems. Applied this result to robust H∞ dynamic output feedback control problem for the systems with structured uncertainty, it is easy to get the solution to robust H∞ dynamic out- put feedback problem,which involves solving two algebraic Riccati equation.
