Using the direct perturbation technique, a general unstable chaotic solution was obtained of the Bose-Einstein condensates trapped in one-dimensional tilted optical lattice potential. The dynamical phase diagram of this system was studied. Theoretical analysis results and the corresponding numerical results showed the chaotic behavior of the system. It was found that Bose-Einstein condensate chaos could be controlled by changing the wave length of the incident laser light or adjusting the system parameters.
