Phase Estimation for Phase-Locked-Loop Ultrasonic Drive

碩士 === 國立中山大學 === 電機工程學系研究所 === 106 === An ultrasonic drive requires frequency locking at its resonance for high vibration efficiency. Phase locked loop is a common approach to achieving this purpose. To fully employ the power of phase locked loop, however, it requires the precise phase information,...
