FREQUENCY SWITCHED CHUA'S CIRCUIT: EXPERIMENTAL DYNAMICS CHARACTERIZATION

Abstract

In this letter the so-called frequency switched Chua's circuit is presented. Its realization is based on the introduction of a switch device into the Chua's circuit, realized by using three State-Controlled CNN cells. The dynamics of this system has been investigated both numerically and experimentally with respect to the frequency of the switch enabling signal. It exhibits different strange attractors, according to the variation of the frequency of the switching signal. Moreover, very strange frequency hysteresis phenomena demonstrating the peculiarity of the introduced circuit have been revealed.
