摘　　要：研究带有界扰动的一类大型互联非线性系统的鲁棒分散控制问题,该系统的第i个子系统的标称模型具有相对阶r_i及指数稳定的零动态,且每个子系统的互联项满足匹配条件.通过子系统状态的线性变换得到鲁棒分散状态反馈控制器,当该控制律作用于系统时,系统的状态能够收敛到原点的一个小邻域内,并给出仿真算例说明该结论的可行性和有效性.The robust decentralized control is considered for a class of large-scale interconnected nonlinear systems with bounded disturbances. The nominal model of the i-th subsystem has a relative degree ri and a zero dynamics with exponential stability; and the interconnection between subsystems satisfies the matching condition. Applying the linear transformation to the states of each subsystem, we obtain the robust decentralized state feedback controllers which ensure the states of the systems to converge to a small region around the origin. A simulation example also shows the feasibility and effectiveness of the conclusion.
