Abstract: Ihis paper studies the fuzzy H. filter design problem for signal estimation of nonlinear discrete-time systems with multiple time delays and unknown bounded disturbances. First, the Takagi-Sugeno(T-s)fuzzy model is used to represent the state-space model of nonlinear discrete-time systems with time delays. Next, we design a stable fuzzy H filter based on the T-S fuzzy model, which guarantees asymptotic stability and a prescribed-infinity index for the filtering error system, irrespective of the time delays and uncertain disturbances. A sufficient condition for the existence of such a filter is established by using the linear matrix inequality(LM)approach. The proposed LM problem can be efficiently solved with global convergence guarantee using convex optimization techniques such as the interior point algorithm. imulation examples are provided to illustrate the design proceure of the present method.

摘要:针对带有多时滞和未知有界扰动的非线性离散系统的信号估计,本文研究了模糊滤波器设计问题。首先,用T-S模糊模型来表示时滞非线性离散系统的状态空间模型然后,我们基于T-S模糊模型设计稳定的模糊滤波器,该滤波器保证了滤波误差系统的渐近稳定性和指定的指标,且与时滞和不确定扰动无关。采用线性矩阵不等式方法,得到了存在这样的滤波器的充分条件。通过像内点法等凸最优化技术,提出的LMI问题可以有效地解出具有全局收敛保证的结果。仿真例子说明了提出方法的设计过程。
