Time for Achieving Controlling Haol-chaos by Typical Controllers

Wavelet function controller,delayed-feedback controller,self-adaptive controller and logarithm-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.
