摘　　要：相互耦合同步法能使混沌系统同步,但是在混沌系统一个参数不匹配时该方法不能使超混沌系统同步.用数值模拟的方法研究超混沌系统参数不匹配情况下的同步,利用相互耦合法和自适应控制同步法在超混沌LC振荡电路中实现了混沌系统一个参数不匹配情况下的混沌同步.当超混沌LC系统两个参数不匹配,甚至超混沌LC系统两个参数相差很大的情况下,该方法均能使超混沌系统达到同步.The mutual coupling method can realize the synchronization of chaotic systems, but when one chaotic parameter is not matched,this method can not realize the synchronization of hyperchaotic systems. In this paper,the method of numerical simulation is adopted to investigate the synchronization of hyperchaotic systems in the case of one parameter being mismatched. The hyperchaotic synchronization is achieved in a LC oscillator by combining the mutual coupling method and the adaptive control method in the case of there being one mismatched parameter in the hyperchaotic system. This method can also achieve the complete synchronization of hyperchaotic LC systems when two parameters of the hyperehaotic LC system are mismatched and even there is a much bigger difference between the two corresponding but mismatched parameters.
