摘 要: 研究一类网络时滞为未知、时变、有界,并且数据传输过程可能存在数据丢包或时序错乱的网络控制系统(networked control system, NCS)故障检测滤波器的设计问题。基于网络控制系统的一种连续时间模型,应用Lyapunov-Krasovskii函数,推导并证明了H∞故障检测滤波器(H∞ fault detection filter, H∞-FDF)存在的依赖时滞的充分条件,并采用一种锥形补技术,将H∞-FDF的求解转化成具有线性矩阵不等式组(linear matrix inequalities, LMIs)约束的最小化问题。最后,给出了求解观测器增益矩阵的迭代算法。
关 键 词: 控制理论与控制工程;H∞故障检测滤波器;网络控制系统;网络时滞;线性矩阵不等式

Abstract: This paper deals with the problem of fault detection filter design for a class of networked control systems (NCSs). Under the assumptions of network-induced time delay being unknown but bounded, packet dropouts and packets out of sequence being unavoidable, a system model for NCSs is firstly introduced in the continuous-time domain. Then an observer-based H∞ fault detection is formulated and, by applying the Lyapunov-Krasovskii functional approach, a delay-dependent sufficient condition on the existence of the H∞ fault detection filter is derived in terms of matrix inequality. Furthermore, an algorithm is proposed to get a feasible solution to the H∞ fault detection filter gain matrices in terms of (linear matrix inequalities LMIs) using a cone complementary technology.
Key words: control theory and control engineering; H∞ fault detection filter; networked control system; network-induced time delay; linear matrix inequality
