Improved results on robust stability of neutral systems with mixed time-varying delays and nonlinear perturbations

Abstract: a b s t r a c tThis paper considers the problem of robust stability of neutral systems with mixed timevarying delays and nonlinear perturbations. Two type uncertainties such as nonlinear time-varying parameter perturbations and norm-bounded uncertainties have been discussed. Based on the new Lyapunov-Krasovskii functional with triple integral terms, some integral inequalities and convex combination technique, a new delay-dependent stability criterion for the system is established in terms of linear matrix ineq… Show more

“…It is well known that time-delays can cause poor performance or instability. Therefore, the problem of delay-dependent stability and stabilization for T-S fuzzy systems with time-delays has been received great efforts by many researchers in recent years [2,[4][5][6][7][8][9][10][11][12][13] because delay-dependent approaches are generally less conservative than delay-independent ones when the sizes of time-delays are small [14].…”

“…However, the foregoing stability criteria for neutral system with time‐varying delay are only applicable to the case when the lower bound of the delay is zero. Recently, delay‐dependent stability for linear system with interval time‐varying delay was investigated in . In , Yu and Lien have obtained the robust stability criteria for uncertain neutral systems with interval time‐varying delay by the free‐weighting matrices, but these criteria are neutral‐delay‐independent.…”

“…Time-delay occurs in various physical, industrial and engineering systems such as biological systems, neural networks, networked control systems, multi-agent systems, and so on [5][6]. It is well known that the existence of timedelay is source of proof performance and instability of dynamic systems [7][8].…”
