【摘要】 以共轭洛仑兹型系统为基础提出一种改进的同步控制方法,应用该方法,给出共轭洛仑兹型系统同步的一组充分条件及共轭洛仑兹型系统与洛仑兹型系统的异结构同步的数学模型,并用数值模拟来验证理论的正确性和有效性.数值模拟结果表明,状态变量的控制参数值越大,对应的状态变量同步所需时间越短;当控制参数的最小值增大时,系统同步时间就减短;当3个控制参数取相同值时,可以通过控制该参数值控制系统同步时间.更多还原

【Abstract】 Based on the conjugate Lorenz type chaotic system,an improved method of chaotic control and synchronization is proposed.Applying this method,a set of the sufficient conditions of synchronization of conjugate Lorenz type chaotic systems and the mathematic model of synchronization with different structure of conjugate Lorenz systems and Lorenz-type systems is given.The numerical simulations illustrate that control parameters are greater,the value of the corresponding state variables synchronize the time required are shorter.When the control parameters of the minimum increases,the system synchronization synchronize time shortened.Under the condition that all of the control parameters are same,the synchronization of time is controlled directly by the parameter values.更多还原
