DC Motor Speed Control Based on Phase-Locked Loop Technique

Introduction was made to the application of phase-locked loop (PLL) technique in the DC motor speed control system. A new type of frequency control circuit of DC motor speed control system based on PLL was proposed to achieve the phase-locked control of motor rotor phase through optical rotational speed instrument. The calculating method of circuit parameters was also provided. The DC motor speed control system with PLL technique is in possession of good dynamic performance and higher stable precision.
