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