Guaranteed cost Hinfin robust control for uncertain multiple time-varying delays systems with nonlinear perturbation is studied by state feedback. The delay is time varying, and the nonlinear perturbations meet linear constraints. Based on Lyapunov-Krasovskii functional, two new guaranteed cost Hinfin robust control results are presented in terms of matrix inequalities technique and nonlinear dealing...
This paper deals with the problem of delay-dependent robust stability for a class of linear systems with multiple time-varying delays and nonlinear perturbations. Based on an integral-equality approach, the integral equality is an improved version of integral inequality and is constructed with free weighting matrices. The free terms are chosen according to the derivative of the Lyapunov-Krasovshii...
Smith predictor is very sensitive to uncertain system with variable time-delay. Using dual-locus diagram method, we first analyse the essence of Smith predictor's sensitivity and present a proposition to illustrate the system stability criteria with relation to system gain and time-delay variation. Then a new modified Smith predictor is proposed to compensate the variable time-delay system with uncertain...
The alpha-robust stabilization condition including system's characteristic roots information is established by applying novel time-delay system robust analysis and design technique in network congestion control issue. The result is presented in the form of linear matrix inequalities (LMIs) problem so that it is easy to be calculated. By solving the corresponding LMI, one can easy obtain the robust...
For the teleoperation of a robot over the IP network, we must deal with the uncertain time-delay because it reduces the stability of the teleoperation significantly. The time-delay is produced by the variable network structure and its imbalanced distributed flows. In this paper, we first analyze the time-delay of Internet and establish a model based on the dynamic IP network traffic characteristics,...
