摘　　要：设计了一类带或不带参数不确定的李普希茨非线性时滞系统的观测器,这类系统的状态方程和测量输出方程中都存在非线性项。分别对存在和不存在参数不确定项的两种情况,提出了一种基于线性矩阵不等式设计状态观测器的方法。数例仿真结果验证了该设计方法的可行性。An observer was designed for a class of Lipschitz nonlinear state delay systems with or without parameter uncertainty.The nonlinearities were assumed to appear in both states and measured output equations.For the both cases with and without norm-bounded time-varying parameter uncertainties,a design method was proposed,in which linear matrix inequalities were solved.A numerical example and the simulating result were provided to demonstrate the applicability of the proposed approach.
