【摘要】 本文在研究了目前国内外温度控制现状的基础上,提出了一种基于ARM的模糊PID温度控制系统。系统采用ARM9微处理器AT91RM9200作为主控制芯片,对温度检测电路和D/A数据转换电路进行了设计;在软件上,对温度检测模块、D/A数据转换模块及控制算法等应用程序进行了开发设计。建立了工业锅炉蒸汽温度控制系统的仿真模型来检测系统性能,分别对常规PID控制和模糊PID控制进行了仿真分析。结果表明模糊PID控制有效的提高了系统对非线性、时变性和不确定性的处理能力,控制效果更好。更多还原

【Abstract】 On the basis of relavant research both at home and abroad,a fuzzy-PID temperature control system based on ARM is proposed.The system adopt ARM9 embedded micro controller as the main control chip,the temperature detection module and D/A D/Ata acquisition module have been designed;In software,the programming of applications of temperature detection module,D/A D/Ata acquisition module and the control algorithm module has been design.A simulation model with the temperature control system of industrial boiler steam has been established.The result show that the fuzzy PID control effectively improve the system capacity,such as nonlinear,time variability and uncertainty,get better control effect.更多还原
