We present a method of anti-control of chaos in Bose-Einstein condensate by applying periodic signals to convert the periodic state into chaotic state. Numerical simulation shows that there are different chaotic orbits corresponding to different modulation intensity and modulating frequency only if the maximum Lyapunov exponent of the system is positive. The phase difference between the two sinusoidal forces added to the Gross-Pitaevski equation plays an important role in anti_control of chaos.
