基于模糊PID的不同液蛋配比控制系统研究
Control system of different ratios of liquid eggs based on fuzzy PID
摘要
Abstract
[Objective]To optimize the ratio control system for egg yolk and egg white(liquid whole egg)in liquid egg production.[Methods]The microcontroller inputs ratio signals of egg yolk and egg white(liquid whole egg)via the touch screen.The frequency of the frequency converter and the speed of the pump are controlled through a fuzzy PID control algorithm.Compared with the feedback signal monitored online by the conductivity meter,a real-time and accurate ratio of egg white and egg yolk liquid is obtained.The performance of the traditional PID algorithm,particle swarm optimization PID algorithm,and fuzzy PID algorithm is compared by Simulink in Matlab software.[Results]The analysis results show that Fuzzy PID has a smaller overshoot,shorter adjustment time,and stronger dynamic response ability.In the ratio test,the liquid egg ratio control system based on fuzzy PID has a maximum conductivity error of 0.17 mS/cm,and the difference between yolk mass content and actual value is 3.4%.The time for the system to reach stability is around 10 s,with a maximum yolk mass fraction error of only 0.8%.[Conclusion]The designed liquid egg ratio control system can effectively reduce ratio errors,respond quickly,and maintain stability.The real-time online monitoring and ratio control are both realized,and the intelligence of the liquid egg production equipment is improved.关键词
