Study on the Speed Control Algorithm of DC Motor Based on the Software Phase-locked Loop Technology

Abstract

The high performance of DC motor speed control system is required under some situations, while the speed control system based on the phase-locked loop technology has its unique advantage in the steady speed precision. Based on the common software phase-locked speed control system, the paper designs the improved software phase-locked speed control system of DC motor. The experiment shows that the insulin pump with the control algorithm of DC motor has enough infusion precision to meet the design requirements.
