چکیده

This paper provides new delay-range-dependent stability criteria in the forms of LMIs for systems with interval time-varying delays. Two cases concerning whether the derivative of the time delay is known are studied. A new estimation method is developed to estimate the nonlinear time-varying coefficients derived from Jenson’s integral inequality more tightly than the existing ones. Along with convex combination and delay partitioning method, less conservative stability criteria are provided by utilizing the new estimation method. Numerical examples are given to illustrate the effectiveness of the proposed method.

GLOBAL ROBUST STABILITY CRITERIA FOR T-S FUZZY SYSTEMS WITH DISTRIBUTED DELAYS AND TIME DELAY IN THE LEAKAGE TERM

The paper is concerned with robust stability criteria for Takagi- Sugeno (T-S) fuzzy systems with distributed delays and time delay in the leakage term. By exploiting a model transformation, the system is converted to one of the neutral delay system. Global robust stability result is proposed by a new Lyapunov-Krasovskii functional which takes into account the range of delay and by making use o...

Delay-range-dependent stabilization of uncertain dynamic systems with interval time-varying delays

In this paper, the problem of delay-range-dependent stabilization criterion for uncertain dynamic systems with time-varying delays is considered. The time-varying delays considered is assumed to be belong to a given interval in which lower bound of delay is not restricted to zero. By constructing a suitable augmented Lyapunov's functional and utilizing free weight matrices, the criterion for st...
