SYNCHRONIZATION OF TWO NON-IDENTICAL HYPERCHAOTIC CIRCUITS

In this work we study synchronization in presence of parameter mismatches between two coupled hyperchaotic circuits. A master-slave scheme based on negative feedback [Kapitaniak et al. (1994)] is considered, where the slave system is designed as an observer of the master. The choice of the observer gains is based on the Master Stability Function in the case that the two circuits are coupled through a unique scalar signal. The approach is experimentally validated, showing how synchronization widely occurs in the range of electronic component tolerances.
