基于嵌入式技术的小型恒压控制系统的设计与实现
Design and implementation of a small size constant pressure control system based on embedded technology
摘要
Abstract
The currently-designed small constant pressure control system has low control precision and poor stability in con-stant voltage mode. Therefore,a small constant pressure control system based on embedded ARM processor is designed. The sys-tem hardware takes the S3C2440 chip as its control core,and extends its hardware circuit through the master control chip pe-ripheral interfaces. The PWM timer of motor driver and S3C2440 chip with subdivision control technology is used to carry out the precision constant pressure control of stepping motor speed. The hardware modules designed with the idea of modularization include master control module,memory module,data acquisition module,motor drive module,communication module,etc. In System Realization Paragraph,the main program flow of the system and the process of constant voltage output control realized with the fuzzy PID intelligent control algorithm are given. The experimental results show that the designed system has high con-trol accuracy and stability.关键词
