| 摘 要： | 当系统采用观测器反馈控制时,常常不能获得系统的输出信息,此时整个系统形成开环。为保证此时系统的稳定性,提出了系统强稳定概念。针对状态向量与控制输入向量中同时具有变时滞,且状态方程与输出方程中同时具有不确定性的线性系统问题,研究了基于状态观测器的系统强稳定鲁棒控制器设计方法。通过求解两个R iccati方程,直接给出了系统的强稳定条件。

| Abstract: | When a system being controlled by feedback control based on state-observer,output information cannot be obtained commonly,the system comes into being open loop.In order to guarantee the system stability,the concept of strong stability is presented.As to the linear systems with time-varying delay both in state and control input,as well as with uncertainties both in sate equation and output equation,state observer based design methods for strong stabilizing controllers of system are studied.By solving the two Riccati equations,The strong stabilizing conditions for time-varying delayed linear system with uncertainties are provided directly. |

| Keywords: | uncertain linear system strong stability Riccati equation time-varying delay |
