New delay-dependent robust exponential stability criteria of LPD neutral systems with mixed time-varying delays and nonlinear perturbations

This paper is concerned with the problem of robust exponential stability for linear parameter-dependent (lpd) neutral systems with mixed time-varying delays and nonlinear perturbations. based on a new parameter-dependent lyapunov-krasovskii functional,leibniz-newton formula,decomposition technique of coefficient matrix,free-weighting matrices,cauchy's inequality,modified version of jensen's inequality,model transformation,and linear matrix inequality technique,new delay-dependent robust exponential stability criteria are established in terms of linear matrix inequalities (lmis). numerical examples are given to show the effectiveness and less conservativeness of the proposed methods. © 2013 sirada pinjai and kanit mukdasai.
