The method of controlling the beam halo - chaos in a strong ion accelerator by constructing a nonlinear feedback controller by using a wavelet function is studied. The numerical simulation results show that the controller constructed by a special function has good halo - chaos control ability, So long as the proper control parameters are adjusted, the four kinds of ion beams with different initial distribution can be controlled optimally.The results are expected to provide an effective reference for the realization of the beam halo - chaos control in the accelerator.
