| The chaos theory has received the widespread attention since it is presented, and applied in many domains. The laser chaos is one of application, and the control and synchronization of laser chaos has great theory significance and application value.In this thesis, the basis and the significance of chaos, and the progress of chaos control and synchronization at home and abroad is first introduced. Then the characteristics of chaos, the methods of chaos control, classifications and method of chaos synchronization are summarized.Secondly, the chaos characteristics of Lorenz-Haken laser chaos are briefly stated, and the chaos mode of Lorenz-Haken laser is derived. The control of Lorenz-Haken laser chaos is realized by using the shooting method, including the periodic orbit control and stability control. The Matlab simulation shows that the Lorenz-Haken laser chaos can go into one, two, four-cycle orbit control and stability, proving that the use of control methods can eliminate initial state of uncertainty in sports, ultimately, the maintenance of accurate balance in the desired state.Finally, the uncertainty stimulated Raman scattering is synchronized with the different structures Lorenz-Haken laser chaos using the adaptive method, and the parameters of the stimulated uncertain Raman laser system is identified. The synchronization controller and parameter identification of the structure is designed based on the stability theory. The results of Matlab simulation show that state variables of Lorenz-Haken system follow stimulated Raman system at strict track under the action of parameter observer and synchronization controller, meaning the stimulated Raman system and Lorenz-Haken system complete synchronization. All parameters of Raman system can be identified, thus proving the observer and parameter identification device effectiveness. |
