This paper is concerned with congestion control for dynamic TCP/AQM networks with random delays. A robust congestion control algorithm is presented based on the H∞ approach, and the system performance is analyzed via linear matrix inequalities (LMIs). Simulation results illustrate the effectiveness of the proposed algorithm.
This paper investigates the problem of fuzzy state feedback robust control for standard discrete-time fuzzy singularly perturbed systems(FSPSs) with time-delay in states. Based on a matrix spectral norm approach, an ε-dependent sufficient condition, which ensures the existence of fuzzy state feedback controller such that the resulting closed-loop system is asymptotically stable, is provided. A simulation...
Through reducing the boundary layer, higher control accuracy can be achieved when applying robust control techniques. However, chattering phenomenon may occur. This paper presents a nonlinear robust controller design in which a dynamic boundary layer is introduced. Theoretical results are presented for characterizing the tracking performance. In particular, the tracking error is forced to converge...
In this paper, the delay-dependent H∞ performance criterion which possesses decoupling structure is derived for systems with time-varying delay. It can reduce conservatism inherent in the classical quadratic method by providing a parameter-dependent Lyapunov function. Then the robust H∞ controller is designed for time-delay systems with polytopic uncertainty. All the conditions are given in terms...
Conventional control strategies of three phase converter are reviewed first in the paper. Then an optimal current control method mixed with PI without small signal linearation. The controller has strongly robustness to load disturbance and system parameter disturbance. At the same time system has high-power factor. The feasibility and advantage of the control scheme is verified by simulation and experimental...
