一类不确定网络控制系统的有界输入保性能控制

Guaranteed cost control and bounded-input for the uncertain networked control system

针对一类不确定的网络控制系统,在满足系统一定性能指标的基础上考虑系统中存在的问题及影响系统稳定的各种不确定因素,应用李亚普诺夫稳定性理论,借助线性矩阵不等式,推导出了闭环系统渐近稳定充分条件,提出了针对性的控制策略,并给出了有界输入保性能反馈控制率,优化了系统的性能。

This paper focus on the uncertain networked control system under the consideration of some problems in the systems and some uncertain factors affecting the systems stability based on guaranteed cost control.The sufficient condition for the uncertain networked control system which is subject to the closed-loop system asymptotic stability and H∞performance is mainly derived based on the Lyapunov stability theory and Linear Matrix Inequality（LMI）.The corresponding control strategy and guaranteed cost feedback controller which can optimalize the system performance are given at last.
