摘要: 考虑非对称耦合映象格子的控制问题, 用线性分析的方法分析了在钉扎控制下系统的稳定性, 同时还分析了耦合的非对称性对控制效率的影响.得出将系统控制到几种稳定状态所需要最小钉扎密度与系统参数间的关系和耦合梯度对控制效率的影响, 并给出了数值验证.钉扎控制用于非对称耦合系统比用于对称耦合系统更加有效, 在相同的钉扎密度下, 可控制区域随耦合梯度的增加而增加.

Abstract: Controlling spatiotemporal chaos in unsymmetrical coupled map lattice is investigated. The stability of the CML with pinning controlling is analyzed with linear analysis, and thecoupled gradient effect on controlling efficiency is analyzed also. The smallestpinning density for controlling a CML to some desired states is given. And the numerical simulations are given. Pinning controlling for unsymmetrical system in more effective then symmetrical system. With same pinning density, the controllingregion is increase with the coupled grade increase.

Key words: chaos, spatiotemporal chaos, pinning control
