【摘要】 提出了一种基于动态面控制(dynam ic surface control,DSC)的超混沌同步方法.在DSC方法中,每一步中虚拟控制器都通过一阶滤波器,从而避免了对一些非线性项的重复求导,使得所设计的控制器克服了backstepp ing方法的复杂性激增缺点.针对系统中存在未知参数的情况,在控制器的设计中引入自适应方法.最后,利用仿真结果验证了方法的有效性.更多还原

【Abstract】 A synchronization method for hyperchaotic systems based on the dynamic surface control(DSC) is proposed.In every DSC design step, the repeated differentiations of certain nonlinear terms is avoided by letting the virtual control pass through a first-order filter.Then,the problem of "explosion of complexity" existed in backstepping methods is eliminated.For the unknown system parameters,an adaptive method is used in the controller design.Finally,the simulation results illustrate the effectiveness of the proposed scheme.更多还原
