Abstract
This paper is concerned with the problem of non-fragile H∞ filter design for nonlinear systems. The nonlinear plant is represented by a Takagi-Sugeno (T-S) fuzzy model. By using the fuzzy Lyapunov function, a sufficient condition guaranteeing the H∞ performance of the filter error is derived. The condition for the H∞ filter design is expressed by a set of linear matrix inequalities (LMIs), which is assumed to have additive gain variations. Finally, the validity of this approach is illustrated by an example.
