【摘要】 pH(酸碱度)控制广泛存在于化工等生产过程之中,属于典型的过程控制对象。pH控制不佳可能会在化工生产过程中造成生产过程波动,质量不稳定,产量降低,原材料浪费,装置腐蚀和环境污染等状况。因此,优良的pH控制对化工生产非常有必要。pH控制过程具有独特的对象特性,这些特性给控制带来了较大的难度。本文在分析以往pH控制方法的基础上,应用传统控制算法——PID结合遗传算法实施pH控制。该控制方法在文中给出了详尽的介绍,并通过仿真验证了其可行性。更多还原

【Abstract】 pH control which is representative control object widely exists in chemical industry.In chemical production process,bad pH control should cause some defects,such as production fluctuation,quality instability,output reduction,raw materials waste,device corrosion and environment pollution etc.Then good pH control is very important to chemical production.PH control process has unique characteristic and brings difficulty on control.This paper analyses pH control means,combines Genetic Algorithm and traditional control algorithm——PID as pH control means,introduces the control means in detail,and proves it effective in simulation.更多还原
