%X The electro-optic effect and the field distribution of Lead lanthanum zirconate titanate(PLZT)transparent ferroelectric ceramic waveplates are reviewed. The feedback single rotatable-variable PLZT waveplate polarization controller is constructed based on the variable retardation and rotatable axes of a PLZT waveplate. For this controller the simulated annealing algorithm is applied to dither optimization considering the limit of phase shift and the endless rotatable axes. Simulated research results show that this controller can transform any varying general input polarization state into an arbitrary linear output polarization state and in the desired direction more than 98% of total light intensity is attained. On controlling the phase shift can vary within 0～2π,so the fluctuation caused by resetting can be avoided.
