Input independent chaos synchronization of switched systems

Input independent chaos synchronization of switched systems is addressed. The synchronization is carried out by designing an observer which involves a switched matrix gain. A special structure of this gain enables both an input independence of the state reconstruction error equation and a global convergence of this equation. Input independence is ensured by a suitable partial pole placement while the global convergence is based on the poly-quadratic stability concept. Those theoretical results would be interesting for possible applications in communications.
