Abstract

This paper proposes a novel approach to designing a fault-tolerant \({H}_{\infty }\) sampled-data fuzzy filter using exponential time-varying gains. The utilization of exponential time-varying gains not only achieves a reduction in convergence time but also provides relaxation in the numerical optimization of design conditions. Also, through the use of a robust control technique, the designed filter is equipped with enhanced fault-tolerant capabilities. In addition, sufficient conditions for ensuring \({H}_{\infty }\)-based state estimation performance are derived as linear matrix inequalities (LMIs) based on the Lyapunov–Krasovskii functional (LKF). Finally, simulation results demonstrate the superior performance of the proposed method when compared to existing methodologies.

为采样数据 T-S 模糊系统设计具有指数时变增益的稳健容错模糊滤波技术
本文提出了一种利用指数时变增益设计容错({H}_{\infty }\ )采样数据模糊滤波器的新方法。指数时变增益的使用不仅缩短了收敛时间,而且放宽了设计条件的数值优化。同时,通过使用鲁棒控制技术,所设计的滤波器具有更强的容错能力。此外,基于 Lyapunov-Krasovskii 函数(LKF)的线性矩阵不等式(LMI)推导出了确保基于 \({H}_\{infty }\) 的状态估计性能的充分条件。最后,仿真结果表明,与现有方法相比,所提出的方法性能优越。
