Proportional and Differential Control of a Nonlinear Capacitor Chaos Circuit

The proportional and proportional-differential feedback control methods are proposed for a three dimensions nonlinear capacitor chaos circuit. The two linear feedback control methods both can lead chaos to the unstable fixed points and various period orbits. The proposed strategies have the advantages of being simple, efficient and easy to implement. Furthermore, the controller does not require any information about unstable periodic orbits of the system. The simulation results show that the proposed methods are valid.
