In this paper, a robust delay-dependent α-synchronization via output feedback for a class of uncertain noise-perturbed time-delayed chaotic systems with unequally perturbed parameters is considered. Based on the Lyapunov-Krasovskii stability theorem and linear matrix inequality (LMI) technique, a criterion is obtained to guarantee that the slave system is robustly α-synchronized to the master system,...
The problem of fuzzy static output feedback H∞ control is investigated for a class of nonlinear systems with time-varying delay. Specifically, the considered system is approximated by a Takagi-Sugeno (T-S) fuzzy model. By using linear matrix inequality (LMI) methods, we design a fuzzy static output feedback H∞ controller, which guarantees asymptotic stability and a prescribed H∞ index for the resulting...
Neural networks and T-S fuzzy systems have been widely used in nonlinear system control. Standard neural network model (SNNM) can be used to describe intelligent systems composed of neural networks or T-S fuzzy models, and so provides a common controller synthesis framework for these kinds of systems. This paper investigates robust output feedback controller synthesis of discrete-time nonlinear systems...
This paper investigates the problem of static output feedback H∞ control for a class of nonlinear systems via a linear matrix inequality (LMI) approach. The considered system is approximated by the Takagi-Sugeno (T-S) fuzzy model. Based on a Lyapunov functional method, we develop a H∞ control law which makes the closed-loop system is asymptotically stable with guaranteed H∞ performance. In contrast...
This paper deals with the problem of robust stability for a class of nonlinear systems. The systems are composed of a linear constant part perturbated by an additive nonlinear function which satisfies a quadratic constraint. A new sufficient condition, formulated in terms of linear matrix inequality LMI, is presented for static output feedback stabilization. Numerical examples are given to illustrate...
The problem of static output feedback fuzzy control for a class of nonlinear fuzzy impulsive time-delay systems is investigated by employing Lyapunov functions. A new scheme of robust fuzzy control via linear matrix inequality (LMI) technique is proposed. The so-called parallel distributed compensation (PDC) idea is employed to design the static output feedback controller. Sufficient conditions for...
