研究具有时变采样周期和数据丢包的网络控制系统的渐近稳定和严格耗散控制问题.针对采样周期时变且在标称周期上下波动,数据丢包数有界,利用参数不确定的方法,网络控制系统建模为一类带有参数不确定的离散时滞系统.构造一个改进的李雅普诺夫–卡拉索夫斯基函数,基于线性矩阵不等式方法及Jensen不等式方法,给出系统严格(Q,S,R)–耗散的充分条件,得到控制器的设计方法.数值实例表明所提出的方法具有较小的保守性,同时也减少了计算量.
The problem of asymptotic stability and strict dissipative control for networked control systems with time-varying sampling periods and data packet loss is studied. For the time-varying sampling period and fluctuation in the nominal period, the number of packet loss is bounded, Method and networked control system are established as a class of discrete time-delay systems with uncertain parameters.An improved Lyapunov-Carrasovski function is constructed, based on the linear matrix inequality method and the Jensen inequality method, (Q, S, R) - dissipation, the design method of the controller is obtained.The numerical examples show that the proposed method is less conservative and reduces the computational cost.
