摘要
为了实现矿井水净化处理工艺过程中混凝剂的准确投加,提出采用前馈控制加反馈控制的方法来实现加药量的控制,其中前馈控制利用统计原理形成的表格模型,反馈控制利用专家知识库形成的模糊控制规则,详细介绍了模糊控制系统的基本原理和构成,给出了模糊控制器的具体设计过程,并利用PLC程序来完成具体的模糊控制算法,最终实现了水处理过程中药剂的准确投加。应用结果表明,该控制系统很好的提高了加药系统的可靠性和稳定性,很大程度上节约了水处理成本。
In order to achieve the mine drainage water purification process dtuing accurate dosing coagulant, fbedforward control and feedback control method to realize the dosage control are proposed. Feedforward control uses the form in which statistical principles formed the model, feedback control uses expert knowledge of fuzzy control rules form. The basic principles of fuzzy control system and the constitution are introduced in detail, the specific design of fuzzy controller is given, ultimately the treatment process accurate dosing in pharmacy is realized, and use the PLC program to perform specific fuzzy control algorithm, The results of application show that the control system is very good to improve the reliability and stability of the dosing system, largely saving water treatment costs.
