采用小波函数控制器、延迟反馈控制器、自适应控制器及对数函数控制器对初始分布为K—V分布的离子束进行束晕-混沌控制。发现强流离子束实现束晕-混沌控制所需要的时间与控制器的选择明显有关,自适应控制器和延迟反馈控制器实现控制较快,小波函数控制器和对数函数控制器实现控制较慢。因此,在可以选择的条件下,人们在应用时应尽量选择合适的控制器。
Wavelet function controller, delayed-feedback controller, self-adaptive controller and loga- rithm-function controller are adopted to control beam halo-chaos for high intensity ion beam with K-V distribution. It is found that self-adaptive controller and delayed-feedback controller need less time to achieve controlling halo-chaos than wavelet function controller and logarithm-function controller. So ,if it can be chosen,it could be the appropriate one.
