摘要
研究了一类时滞大系统的分散弹性自适应控制器的设计问题.当控制器增益摄动范数有界但上界未知时,采用自适应方法,给出了系统一致有界稳定的条件和控制器的设计方案,且该控制器具有在线调整的功能.并给出了特例情况下,即控制器增益摄动范数有界且上界已知时,闭环系统可镇定的充分条件和相应弹性控制器的设计方案.数值算例说明了设计的可行性和有效性.
This paper considers the resilient controller design for a class of large-scale delay systems with adaptive approach. The controller perturbation is norm-bounded. When the upper bound is unknown, a sufficient condition of uniformly ultimately bound for the system is proposed. And by adaptive approach, the controller design can be tuned on-line. Furthermore, as a special case, namely the upper bound is known, a suf-ficient condition for the stabilization of the system and the controller design are derived. Finally, a numerical example illustrates the effectiveness and the availability for the design.
