Chaotic Control and Synchronism with Noise Interference Based on State Observation

The control method of state modulator is used to control chaos in the paper. The state controller is constructed on the basis of the system equation in the presence of noise interference and used to control the chaotic Lorenz system interfered by measure and input noise. As the operation range of state observation is changed, the method can stabilize the original equilibrium point or stabilize the systems to the new equilibrium point. The simulation results prove that the method is effective.
