摘要
提出求解时滞系统的H~∞状态反馈控制问题的代数方法。基于代数Riccati方程,给出了时滞系统的闭环传递函数H~∞范数小于等于某一给定界γ的充分条件,并通过适当构造Lyapunov函数,证明了闭环时滞系统是渐近稳定的。
This paper presents an algebraic approach for solving H∞ state feedback control problem for time delay systems. Based on algebraic Riccati equation, a sufficient condition is given that H# norm of the closed - loop transfer function is not greater than a prescribed lever γ. The closed - loop time delay system is proved to be asymptotically stable through properly constructing a Lyapunov function.
