Abstract

This article deals with the design of robust H(infinity); filter for singular systems in general form, subject to bounded time-varying uncertainties. The aim is to design linear admissible descriptor filters that ensure a guaranteed bound on the L(2) gain of the operator from the noise signals to the estimation error signal, irrespective of the time-varying uncertain parameters. A strict LMI-based method is proposed to the robust H∞ filter design employing affine Lyapunov functions. A numerical example is presented to show the efficiency of the proposed method.
