摘要:

研究了一类具有控制输入时延的离散系统H可靠性控制问题,提出了具有实际意义的服从某种概率分布的随机故障模型。假设输入时延符合齐次Markov分布,在控制器的设计中利用了控制器的历史信息, 把系统转换为无时延的Markov 跳变系统,根据Lyapunov稳定性理论和线性矩阵不等式(linear matrix inequality, LMI)方法,给出了故障分布依赖的H均方稳定且具有H范数界γ的容错控制器解的存在条件。最后, 通过算例验证了本方法的有效性。

Abstract:

An H reliability control is investigated for a class of discrete-time systems with stochastic input delays and actuator failures. A new practical fault model obeying a certain probability distribution is proposed. Assuming that the input delays obey a homogenous Markovian chain and utilizing the historic information of the controllers, an augmented Markov jump system (MJS) is developed. By applying Lyapunov stability theory and linear matrix inequality (LMI) technology, the sufficient conditions is given for the existence of  H reliability control based on fault distribution dependence with mean square stableness. An illustrative example is exploited to show the effectiveness of the proposed design procedureness.
