Conference Proceeding: Development of a decentralized robust controller for uncertain large-scale systems with control delays
[show abstract] [hide abstract]
ABSTRACT: This paper presents a decentralized robust controller design for a class of interconnected dynamic systems with control delays and parametric uncertainties. The parameter uncertainties are considered to be unknown but norm-bounded. By applying Lyapunov's stability theorem, two new delay-dependent sufficient conditions are established in terms of linear matrix inequalities, and linear memoryless state feedback controllers are designed to maintain the robust stability for the class of systems under study. It is shown that either no tuning procedure is required or only one parameter from each inequality needs to be tuned. Two examples are presented to demonstrate the application of the results presentedSystems, Man, and Cybernetics, 2000 IEEE International Conference on; 02/2000 -
Conference Proceeding: Robust analysis and synthesis for delayed systems with rank-1 type uncertainties
[show abstract] [hide abstract]
ABSTRACT: This paper deals with the problem of robust stability analysis and synthesis for systems with rank-1 type uncertainties and multiple state delays. A new delay-dependent criterion is presented for the stability of unforced nominal delayed systems. Based on the obtained criterion, a new linear matrix inequality (LMI) approach is developed for the robust stabilization of a class of uncertain delayed systems via a linear memoryless state feedback control law. The results are dependent on the size of the delays and are given in terms of LMIs. The presented method does not require a tuning procedure for scalars and/or matrices and produces results that are less conservative than delay-independent results. Finally, two illustrative examples are presentedSystems, Man, and Cybernetics, 2000 IEEE International Conference on; 02/2000
