چکیده
This paper investigates the problems of asymptotic and robust stability for large-scale discrete state-delayed systems. By means of discrete-type sum inequality approach, an augmented Lyapunov-Krasovskii functional and discrete-type singular model transformation strategy, a new delay-dependent criterion is derived in order to guarantee the robust stability of the above systems. The proposed stability criterion is also used for testing the asymptotic and robust stability of single system with constant time delay, and is expressed in terms of the few-variable-based linear matrix inequality (LMI), which is convenient to get the optimal stability result and can reduce the computational time via LMI toolbox in MATLAB software. Finally, an example is used to show the less conservative result of the proposed approach compared with the previous one.

In this paper, we investigate the delay-dependent robust stability of fuzzy Cohen-Grossberg neural networks with Markovian jumping parameter and mixed time varying delays by delay decomposition method. A new Lyapunov-Krasovskii functional (LKF) is constructed by nonuniformly dividing discrete delay interval into multiple subinterval, and choosing proper functionals with different weighting matr...
متن کاملEigenvalue Assignment Of Discrete-Time Linear Systems With State And Input Time-Delays
Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...
متن کاملA new switching strategy for exponential stabilization of uncertain discrete-time switched linear systems in guaranteed cost control problem
Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
