| Abstract: | The nonlinear dynamics characteristics and stability of the Lorenz system are analyzed by adopting nonlinear control theory. A method for designing the strength-period-feedback controller is put forward. The chaotic behaviors of the Lorenz system are controlled by chaotic control methods which are called period feedback control. Theories of these methods are analyzed and simulated numerically. By using the method, the chaotic systems can be controlled in some equilibrium states or some vibrational cyclical states. With the change of control parameters, the typical variation of physical state is studied to expand the applications of Lorenz chaotic systems. |
