摘要: 针对执行器故障和概率转移矩阵部分未知的情况,研究了一类离散Markovian跳变系统的可靠控制问题.设计有效的状态反馈可靠控制器,不仅使得闭环系统在无故障的情况下是随机稳定的,而且在执行器出现故障的情况下还仍然使得闭环系统是随机稳定的.用一组耦合可解的线性矩阵不等式给出了可靠控制器的可行性条件.数值算例表明了所提方法的可行性和有效性.

关键词: Markovian跳变系统, 可靠控制, 执行器故障, 概率转移矩阵部分未知, 线性矩阵不等式

Abstract: Due to the actuator failures and partly unknown transition probabilities, reliable control problem was studied for a class of discrete linear Markovian jump systems. A reliable controller based on the state feedback method was designed to make the closed-loop systems randomly stable not only when all actuators are operational, but also in case of some actuator failures. The solvability condition of controllers could be equivalent to a feasibility problem of coupled linear matrix inequalities(LMIs). A numerical example demonstrated the feasibility and effectiveness of the proposed design.

Key words: Markovian jump systems, reliable control, actuator failure, partly unknown transition probabilities, linear matrix inequality(LMI)
