摘　　要：以Lorenz系统为对象,基于同步理念,将滑模控制技术应用于混沌系统同步控制器的设计.该方法在系统单状态同步控制的基础上,通过设计合适的滑模控制器和参数自适应律,实现了结构相同而参数互异混沌系统的渐近同步.仿真结果表明,该方法可以很好地达到同步控制要求,验证了所提方案的可行性.Due to the noise,disturbance and the system instability,the parameter disturbance is hard to be avoided in chaotic synchronous secret communication between two systems in which their parameters are the same,even formerly synchronous system will lose synchronization or show comparatively big error.The text takes famous Lorenz system as object and applies sliding-mode controlling technology in designing synchronous controller of chaotic system based on synchronous theory.It realizes the system gradual synchronization of chaos with the same structure and synchronous control through designing proper sliding principle. Simulation results show that the method effectively. different parameters based on the single state -mode controller and parameter self- adapting is feasible and can realize synchronous control
