A new feedback control of a modified Chua's circuit system

A feedback controller is designed to suppress chaotic states of a modified Chua's circuit system. This controller is composed by the following two portions. One is the feedback part which constructs an equilibrium manifold by modifying the dynamics of the system. The other is the proportional feedback part which will control the system to desired stares on the equilibrium manifold. The advantage of this method is that with this closed-loop controller the system attains faster settling time than the systems using previous controllers. Also, it will eliminate the tracking error without using other integral controllers.
