A High-precision Control Method for Synchronization

Wei Wang

Abstract

The implementation method for traditional synchronization prediction is introduced and its characteristics and limitations are analyzed. A high-precision synchronization algorithm is proposed by exactly describing the phase-angle difference trajectory with the fitted curve based on the least square method and solving the accurate moment of zero phase-angle based on iterative solution. The high-precision of this control method is proved by simulation experiments.
