A note on robust stability analysis of chaos synchronization

Robust stability analysis of a class of synchronized systems is addressed i n this work. The problem is focused departing from the mu -analysis of the H-infinity control theory. Main question is, if two chaotic systems behave in synchronous way, how stable is the synchronized behavior? A quantitative measure of the robustness margin of the chaotic synchronization is studied in this work. The class of synchronized systems comprises second-order dri ven oscillators. An illustrative example shows the results of the robustnes s issues on the chaotic synchronization. (C) 2001 Elsevier Science B.V. All rights reserved.
