Abstract :
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.
