An algorithm of controlling chaos, combining chaos prediction with improved OGY method, is proposed. First, the OGY method is improved so that chaos system is stabilized to different targets. Then the state evaluation of the system is gained by using phase space predictive algorithm for chaos, and the control quantity is produced to make chaos system quickly move into its control neighborhood. Compared with general chaos control methods, this method speeds up stabilization process for chaos system. Simulation results show that this method is effective.
