时滞不确定组合系统的鲁棒分散输出控制

讨论了时滞不确定组合系统的鲁棒分散输出控制问题．不确定项存在于子系统内部，可以是非线性或时交的：而且时滞存在互联项中，并满足匹配条件．不确定项是有界的，但界是未知的．利用自适应律来估计未知的上界，设计出分散无记忆输出控制器．基于Lyapunov稳定性理论和Lyapunov-Krasovskii函数，该控制器能够保证闭环系统的解是终极一致有界的．最后的仿真结果说明该设计方法是有效的．

Robust Decentralized Output Feedback Control for Uncertain Delay Composite Systems

The problem of robust decentralized stabilization is discussed for a class of uncertain delay composite systems. The system under consideration is with uncertainties in each subsystem and delayed states perturbations in the interconnections. The upper bounds of the uncertainties are assumed to be unknown. The adaptive laws are proposed to estimate such unknown bounds, and by making use of their updated values, a class of decentralized memoryless output feedback controllers is constructed. Based on Lyapunov stability theory and Lyapunov- Krasovskii function, the solutions to the closed-loop composite systems can be guaranteed to be uniformly ultimately bounded. Simulation results show that the control scheme is effective.
