The exponential stabilization problem of a class of linear systems with actuator saturation is addressed in this paper. In an approach different from the previous results where the continuous controllers are used all the time, here the periodically intermittent control is proposed to ensure the exponential stability of the closed-loop systems. An exponential stability criterion is suggested using...
A sliding mode controller is designed for the longitudinal dynamics of a generic hypersonic vehicle. A generic nonlinear longitudinal dynamics model for wedge-shaped vehicle is used. Based on the dynamic inverse control, the sliding mode is adopted with the reaching law that contains a linear-quadratic controller. Optimal control techniques can be applied to search the parameters of linear-quadratic...
This paper considers guaranteed cost control problem for systems with saturating actuators and input delays. By using Razumikhin stability theorem, a linear state feedback control law is found, ensuring not only the closed-loop system's stability but guaranteed cost index. And the problem of designing the optimal guaranteed cost controller is converted to a convex optimization problem within the framework...
This note deals with the absolute stability of Lur'e control systems with time-varying delay. An augmented Lyapunov functional is introduced to establish some new stability criteria. First, for the nominal system, we develop some new stability conditions, by considering the additional useful terms and introducing some free-weighting matrices. In the proof of our results, we introduce some useful lemmas...
This note deals with the delay-dependent stability and stabilization of linear system with state and input delays. Firstly, for the nominal system, by introducing the augmented Lyapunov functional and some free-weighting matrices, new delay-dependent stability and stabilization criteria of the system are presented. Then, these new conditions are extended to handle norm-bounded uncertain systems with...
In this paper, we consider the problems of robust stability and stabilization of Lurpsilae control systems with time-varying delay. Firstly, by making use of an integral inequality, some delay-dependent robust stability conditions of the system are presented. Then, a sufficient stabilization criterion is established in the terms of linear matrix inequality (LMI), based on the above stability condition...
This paper considers the problem of robust stability for Takagi-Sugeno fuzzy systems with time-varying delays and norm-bounded uncertainties. By choosing a more general Lyapunov-Krasovskii functional and using some slack matrix variables to express the relationship between the system matrices and the terms of Leibniz-Newton formula, a new less conservative delay-dependent condition for robust stability...
This paper deals with the stability analysis and controller design of linear systems with state delay and input saturation. First, a delay-dependent stability criterion is derived within the framework of linear matrix inequalities by using some free matrices to express the relationship of the terms in the Leibniz-Newton formula. Then the problem of designing linear state feedback laws which guarantees...
This paper is devoted to the absolute stability analysis of Lurie systems with time delay. A new delay-dependent Lyapunov function analyzing approach is proposed to reduce the conservativeness in computing the upper bound of the maximum allowed delay. Some new stability conditions are developed in terms of linear matrix inequalities. Examples are provided to demonstrate the reduced conservatism of...
For the single-loop SISO system which has pure time delay in its feedback loop, several properties of the root-locus as time lag tau varies were studied, including the symmetry of the loci, tau rarr 0 + and tau +infin points, loci and breakaway points on the real axis and intersections with the imaginary axis, etc. The effect on the system stability while time lag varies was also investigated on the...
The problem of delayed feedback control for a class of time-delay chaotic systems is considered in this paper. A novel sufficient delay-dependent condition for stabilization with less conservatism is derived based on the Lyapunov stability theory and linear matrix inequalities technique. A numerical example is given to illustrate the effectiveness of the proposed method
