摘 要: | 本文研究了一类具有关联延迟和系统参数不确定的非线性大系统的分散控制问题,系统的匹配/非匹配不确定参数范数有界。首先基于状态观测器设计时延独立的动态输出反馈控制律,并根据 稳定性理论推导并证明了在该控制律作用下系统稳定的充分条件。最后给出一个数值例子来说明本文结果的可行性,仿真结果表明设计出的控制器不仅使得闭环系统稳定而且保证系统不受参数不确定和时延的影响。

Abstract: | In this paper ,the problem of decentralized control is studied for a class of time-varying nonlinear large-scale systems with interconnect-delay , in which both unmatched uncertainties and matched uncertainties are considered by norm bounding functions . Based on the state observer, a delay-independent dynamic output feedback controller is presented to the controlled systems, With the stabilization theory , a sufficient condition for the closed-loop system’s stability is derived. Finally, a numerical example is provided to illustrate the effectiveness of the paper’s result. it not only shows close-loop stability but also illustrate the system are unaffected when uncertainties and delay are present in the subsystems and interconnections. |
