Abstract :
A study of a phase-locked speed control system is presented for a PM DC motor, focusing on the out-of-lock operation. System behavior is discussed for each case, while acquisition operation is described by phase plane analysis and capture mechanism is explained. Experimental results for a system developed are also given
