NONLINEAR H-INFINITY SYNCHRONIZATION OF LURE SYSTEMS - DYNAMIC OUTPUT-FEEDBACK CASE

In this letter we introduce a new master-slave synchronization scheme for Lur'e systems, which makes use of vector field modulation and dyna mic output feedback in order to recover a message signal, The synchron ization scheme is represented in standard plant form according to mode rn control theory, I/O properties of the scheme are analyzed using a d issipativity approach with a quadratic storage function and a supply r ate with finite L-2-gain. The method avoids transmission of the full s tate vector, The controller design is based on a matrix inequality, co rresponding to nonlinear H-infinity synchronization. The new scheme is illustrated on Chua's circuit.
