Experimental variable event based control for Chua and Gonzalez chaotic circuits

摘要

This paper shows an experimental hybrid technique with several variants for controlling chaotic systems tested with two electronic circuits implemented using commercial components: The Chua circuit and the Gonzalez circuit. The control methods are based on variable event condition automatically adjusted to system dynamics without mathematical model knowledge. A tuning procedure for plant operator has been proposed and applied for both chaotic systems. The analyzed experimental control techniques present satisfactory results, where the objective is to stabilize the behavior of real circuits in periodic orbits; which demonstrates the applicability of the proposed control methods in the analyzed systems.
