基于模糊PID算法的净化空调监控系统
摘要
Abstract
Purify air conditioning control system to pharmaceutical companies based on fuzzy PID (proportion integration differentiation)algorithms was designed.This system mainly consisted of four parts:host computer,the next crew,field instrumentations,and control algorithms.Industrial PC (personal computer)and programming software of Configuration King 6 .5 1 were used in the host computer.The next crew used Siemens S7-200PLC (programmable logic controller),its expansion modules and a modular approach to program,and it was also accompanied by the MT6070ih touch screen operation.Field instruments were mainly composed by temperature and humidity sensors JWSL-5ATD,EE65 air velocity transmitters and ML7420A valve actuator.The fuzzy PID control al-gorithm was designed based on the combination of fuzzy control and PID control,and the PID control was based on fuzzy rules,query fuzzy matrix table to obtain parameter self-tuning,then it could ad-just the parameters of PID in real-time to achieve effective and accurate control of the system.The running results show that the overshot is reduced by 9 .1% and the response time of this system rea-ches a 13.2% reduction compared with conventional PID control,so the control effect is greatly en-hanced.关键词
