Active control isolation for the Lorenz chaotic vibration with a simple method

On the basis of analyzing traditional control methods and in combination with sliding mode control theory, a simplified method of sliding mode control is given in order to eliminate the destructive chaotic movements in apparatus. Furthermore, on mathematical analysis and demonstration to sliding mode control and on observing the simulation experiments, the influence relation between the feedback varying of state variable in Lorenz system and chaotic system boundedness is defined. The eliminating wave controller which is set up by this simplified method can isolate Lorenz chaotic vibration and avoid apparatus damage. Simulation results show that the method is effective.
