研究一类比较广泛的非线性组合大系统的分散鲁棒镇定问题。给出了检验这类非线性组合大系统可分散鲁棒镇定的条件，该判别条件只涉及到近似线性化子系统的可镇定性与系统的耦合项，而且无须通过构造Ｌｙａｐｕｎｏｖ 函数来判别闭环系统的稳定性。仿真结果表明该方法是有效的。
The decentralized robust stabilization for a class of nonlinear systems with large scale is studied. The condition of verifying the decentralized robust stabilization for such large-scale nonlinear systems is given. The criterion only relates to the coupling between the calibratable and the system of the approximating linearized subsystems, and does not need to construct the Lyapunov function to judge the closed-loop system Stability. Simulation results show that this method is effective.
