摘      要：We investigate the exact ac control of two periodically driven and weakly coupled Bose-Einstein condensates in a double-well *** employing two balance conditions we construct new exact Floquet solutions with the degenerate Floquet energy,and give the balance region on the parameter *** is revealed that for some different parameters in the balance region the Floquet solutions exactly describe the macroscopic quantum self-trapping,nonlinear coherent construction and destruction of quantum tunneling,***,we can accurately perform the coherent control by suitably adjusting the system parameters.
