本文对一类具有相似性的不确定非线性组合系统设计了鲁棒控制器 .对不确定性只要求一个已知的可能函数界 ,互联的强度由非减函数限制 ,减弱了对互联项的要求 .我们利用系统本身的相似性 ,简化了设计过程 .所得控制器保证系统的渐近稳定性 . In this paper, we design a robust controller for a class of uncertain nonlinear systems with similarities. For uncertainties, we only need a known possible function bound, the strength of the interconnect is limited by non-decreasing function, We use the similarity of the system itself to simplify the design process and the resulting controller guarantees the asymptotic stability of the system.
