| 摘 要： | 针对一类具有系统参数摄动、时滞关联和外界干扰的线性大系统，提出了一种基于Lyapunov稳定性理论的分散变结构自适应控制方案。通过引入积分滑模和能在线估计不确定性扰动与时滞关联的界的自适应算法，保证了闭环系统的渐近稳定性，实现了系统的鲁棒自适应控制。该方案具有较强的工程实用性，算例仿真的结果表明了该控制方案的可行性。

| Abstract: | A decentralized variable structure adaptive control scheme for a class of linear large-scale systems subjected to system parameter variations, time-delay interconnections and external disturbances is proposed based on the Lyapunov stability theory. An adaptation algorithm that can adapt the unknown upper bounds of the uncertainties and time-delay interconnections is introduced as well as integral sliding mode, so that the asymptotical stability of the closed-loop system is guaranteed, and the robust adaptive control can be achieved. The proposed scheme is very simple for implementation. An example is given to demonstrate the feasibility of the proposed control scheme. |
