摘要
研究了带有执行器故障的连续时间系统的可靠的时滞状态反馈控制问题.利用Lyapunov稳定性理论和线性矩阵不等式方法,给出了连续系统存在可靠时滞状态反馈控制器的LM I形式的充分判据,该判据是时滞相关的.所设计的时滞状态反馈控制器可以容忍执行器的一定故障,并且保证整个闭环系统是渐近稳定的.
After a research on the feedback and control of the reliable time-lag of continuous-time systems with actuator failures. By using Lyapunov stability theory and linear matrix inequality (LMI) approach, the paper has also presented the sufficient and lag-dependent criteria for determining the existence of the reliable time-lag feedback controller in LMI form. The feedback controller thus designed proves to be tolerable to certain failures while guaranteeing the asymptotic stability of the whole closedloop systems.
