摘要 针对一类通信受限的网络控制系统,研究其随机稳定性和H∞控制问题.考虑到系统存在随机丢包、时延、对数量化和概率传感器故障等因素,提出一种新的网络控制系统模型.基于Lyapunov稳定性理论,得到了系统随机稳定性的充分条件,并利用线性矩阵不等式技术,给出了系统H∞控制器的设计方法.数值仿真算例验证了所得结论的有效性. This paper is concerned with the problems of H_∞ control for networked control systems with communication constraints. An improved networked control system model is proposed, while the effects of logarithmic quantization, packet dropout, delay and probabilistic sensor fault are considered simultaneously. Sufficient condition for the stochastic stability of the closed-loop system is given in terms of linear matrix inequality. A controller is designed such that the closed-loop system is stochastic stable and achieves the given disturbance attenuation level. Numerical example illustrates the effectiveness of the proposed method.
