LMI Robust Control of PWM Converters: An Output-Feedback Approach

An Lmi Approach to Robust Stabilization of Networked Control Systems

The problem of robust stabilization of discrete-time uncertain networked control systems (NCSs) in the presence of packet losses and transmission delays is studied. We model such systems as discrete-time nonlinear systems with delayed input. Sufficient conditions on the stabilization of the NCSs are presented. Stabilizing state feedback controllers can be constructed by using the feasible solut...

An LMI Approach to Robust Congestion Control of ATM Networks

In this paper, ATM network congestion control with explicit rate feedback is considered. In ATM networks, delays commonly appear in data transmission and have to be considered in congestion control design. In this paper, a bounded single round delay on the return path is considered. Our objective is to design an explicit rate feedback control that achieves a robust optimal 2 H performance regar...

An LMI Approach to IMC-Based Robust Tunable Control

This paper presents a linear matrix inequalities (LMI) approach to robust tunable control. This controller design technique provides a new on-line tuning strategy for industrial process control systems. The tuning strategy is based on the performance robustness bounds of the system and knowledge of the plant uncertainty’s weighting function, which may change with time. The internal model contro...

ROBUST $H_{infty}$ CONTROL FOR T–S TIME-VARYING DELAY SYSTEMS WITH NORM BOUNDED UNCERTAINTY BASED ON LMI APPROACH

In this paper we consider the problem of delay-dependent robustH1 control for uncertain fuzzy systems with time-varying delay. The Takagi–Sugeno (T–S) fuzzy model is used to describe such systems. Time-delay isassumed to have lower and upper bounds. Based on the Lyapunov-Krasovskiifunctional method, a sufficient condition for the existence of a robust $H_{infty}$controller is obtained. The fuzz...
