Complete practical synchronization of hyperchaotic circuits via a scalar signal

In this paper an approach to achieve a complete practical synchronization of hyperchaotic circuits with parameter mismatch via an impulsive scalar signal is presented. The chosen scalar signal is constituted by a sequence of samples of selected state variables alternatively transmitted for identical time frames. The approach is effectively applied to hyperchaotic circuits with parameter mismatch constituted by two bidirectionally coupled Chua's oscillators.
