H_∞ Filtering for Nonlinear Systems with Time Delays via Takagi-Sugeno Fuzzy Model

Abstract:

State estimation is an important topic in controller design. H_∞ filtering problem is discussed for fuzzy dynamical systems with time delays by using Takagi-Sugeno (T-S) model. Fuzzy H_∞ filter is obtained such that the filtering error system is stable and guarantees a prescribed estimation error level. Delay-dependent Lyapunov functional approach is employed to lower the conservativeness of the filter design. Therefore, the results of fuzzy H_∞ filter are delay-dependent. An example is given to illustrate the proposed results.
