In this paper, we consider the problem of designing Hinfin static output feedback controller for systems with delayed state, delayed input and sensor failure. Two sufficient conditions for the existence of Hinfin output feedback controllers are presented. Furthermore, by using variable transformation and Schur complement, the obtained result can be rewritten as a matrix inequality representation....
This paper deals with the problem of standard feedback control for a class of time-delay chaotic systems. A new delay-dependent condition for stabilization with less conservatism is derived in terms of linear matrix inequalities. In order to obtain a lower controller gain, an optimization algorithm is proposed which involves some constraints to restrict the size of gain matrix. A numerical example...
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
