研究了Lurie复杂网络混沌系统的保性能控制问题的保性能控制问题,基于Lyapunov稳定性理论和线性矩阵不等式处理方法,得到了系统存在最优保性能控制律的充分性条件,即Ω1=P(L1C+K)+(L1C+K)TP+σiεPTP+Q+KTRK+T〈0,Ω2=ε-1 NσiATA-T〈0。而对应的Lurie非线性复杂网络系统存在最优保性能控制律的充分条件为:Ω3=P(L1C+K)+(L1C+K)TP+σiεPTP+Q+KTRK+T〈0,Ω4=ε-1 NσiL2ATA-T〈0。所得结果以LMI形式表示,便于利用Matlab进行求解。
The problem of guaranteed cost control of Lurie complex networks chaos systems is studied in the paper. Based on Lya- punov stability theory and LMI techniques, sufficient conditions for the existence of guaranteed cost state feedback controller of Lu- rie complex networks chaos system is derived. Ω1=P(L1C+K)+(L1C+K)TP+σiεPTP+Q+KTRK+T〈0,Ω2=ε-1 NσiATA-T〈0. The sufficient conditions for the existence of guaranteed cost state feedback controller of Lurie nonlinear complex networks is as following:Ω3=P(L1C+K)+(L1C+K)TP+σiεPTP+Q+KTRK+T〈0,Ω4=ε-1 NσiL2ATA-T〈0. The result is given in LMI, So it is convenient to realize in Matlab.
