Abstract :
A novel adaptive digital pump (phase/voltage) controller (ADPC) is presented for use in phase-locked servo systems without utilizing RC loop filters and high line-density encoders. The proposed ADPC is a multirate processor, of which the linear discrete-time model for the digital pump phase-locked servo system (DPPLS) is constructed. Simulation results that verify the theoretical work are also conducted.
