Abstract:

Speed control of d.c. motors by phase-locked loops PLL is becoming increasingly popular. Primary interest has been in employing PLL for constant speed control. This thesis investigates the theory and techniques of digital PLL to speed control of a brushless d.c. motor with a variable speed of operation. Addition of logic controlled count enabledisable to a synchronous updown counter, used as a phase-frequency detector, is shown to improve the performance of previously proposed PLL control schemes.
