将混沌控制方法——参数切换法——应用于分数阶混沌系统,可以得到稳定的吸引子,维持了分数阶混沌系统的动力学稳定.该方法在一个相对较短的时间周期,通过在一组可供选择的数值内切换系统的一个可控参数来实现,合成的稳定吸引子很好地反映了全局吸引子的数值逼近,且与平均吸引子实现了很好的匹配,达到了混沌控制的目的.仿真结果表明,该方法具有鲁棒性和无损性,可以有效地实现混沌控制.“,”The application of the parameter switching algorithm (PSA)-a new chaos control algorithm-into fractional order chaotic systems brings a stable attractor that maintains the dynamical stability of systems.The PSA works by switching controllable parameters in a given range within a short period.The attractor obtained from this method has been proven to reflect the digital approximations of global chaotic attractors and to match those of average attractors as well.Simulation results show that the PAS is robust,nondestructive,and able to realize chaos control.
