摘要 研究一类不确定非线性时变时滞系统的鲁棒H∞滤波问题,其中假定非线性项满足全局Lipschitz条件.利用S-procedure方法处理非线性项,避免了在Lyapunov-Krasovskii泛函导数中对非线性项和其他交叉项的界定.所提出方法具有更低的保守性,仿真实例证明了该方法的有效性. The problem of robust H∞ filtering for a class of uncertain nonlinear systems with time-varying delay is studied. The nonlinearities are assumed to satisfy global Lipschitz conditions. S-procedure is applied to process the nonlinearities, and avoid bounding of the cross terms of nonlinearities and other terms in derivative of Lyapunov- Krasovskii functional. So the proposed method has less conservativeness. Simulation example shows the effectiveness of the proposed method.
