摘　　要：研究了一类大型互联非线性不确定系统的分散鲁棒几乎干扰解耦问题,通过子系统状态的线性变换,得到分散状态反馈控制律。当状态反馈控制律作用于该系统时,无扰动输入的闭环系统是全局渐近稳定的,而对允许的不确定性,干扰抑制的大小可以任意小,且控制器的设计也无需解任何的Hamilton-Jacobi方程或不等式。This paper studies the problem of decentralized robust almost disturbance decoupling for a class of large-scale interconnected nonlinear systems with uncertainties. Decentralized state feedback control laws are obtained by using the linear transformation of the states of each subsystem.When the state feedback control laws are applied to the systems, the closed-loop systems without exogenous input are globally asymptotically stable and the level of disturbance attenuation can be made arbitrarily small for all allowed uncertainties,and no Hamilton- Jacobi equation or inequality is needed for the controllers design.
