  • 研究了中心力场中螺旋波和时空混沌的控制问题.通过外界机械力旋转系统来产生中心力场,数值计算表明:该方案可以很好消除Fitzhugh-Nagumo 和Panfilov系统的螺旋波和时空混沌,即使在外部力场作用一小段时间 (大约20到50时间单位)后,系统也将很快达到均匀稳定态. 而且该方案对于噪声具有一定的鲁棒性,与所选择的模型无关.

     

    Suppression of spiral in centric field is investigated. The spiral is suppressed by circumrotating the system with mechanical force. It is the first time spiral is supressed and spatiotemporal chaos dispelled using this scheme. The Fitzhugh-Nagumo equation and Panfilov equation are investigated, and numerical simulation shows that the scheme is effective and robust to certain white noise.
