The spatial structure of a Bose-Einstein condensate loaded into an optical lattice potential is investigated and spatially chaotic distributions of the condensates are revealed. Through changing the s-wave scattering length by using a Feshbach resonance, the chaotic behavior can be well controlled to enter into periodicity. Numerical simulation shows that there are different periodic orbits according to different s-wave scattering lengths only if the maximal Lyapunov exponent of the system is negative.
