The Design of Digital Servo-Position Control System Based on LM629

摘要

正The paper is concerned with the digital design of the system of servo-position control for medium-low power DC motor.The paper will be focused on the digitization design of the system.Principle of PWM will be given first in this paper.According to the theory of PWM rules and the knowledge of computer control technology,the paper will design the digital servo-position system that has a good characteristic of stability and dynamic response.
