  We investigate coherent control of single particles held in a bipartite
optical lattice via a combined high-frequency modulation. Our analytical
results show that for the photon resonance case the quantum tunneling and
dynamical localization depend on the phase difference between the modulation
components, which leads to a different route of the coherent destruction of
tunneling and a simple method for stabilizing the system to implement the
directed transport. The results could be referable for manipulating the
transport characterization of the similar tilted and shaken optical or
solid-state systems, and also can be extended to the many-particle systems.
