摘要
针对目前稀土熔盐电解工艺自动化水平较低,本文提出研究稀土熔盐电解智能控制系统。构建智能控制系统的总体框架,研究智能控制系统的关键技术,提出采用模糊自适应PID控制算法协调控制加料量和电解电源,实现对电解槽熔盐温度的实时调整。研究的智能控制系统在6 kA熔盐电解槽进行了实验,实验结果表明,该智能控制系统能够自适应调整电解槽熔盐温度,使得温度偏差在±0.9%范围内,且系统性能稳定,实用性强,为实现稀土熔盐电解工艺的智能化管理提供一定的技术指导。
Due to the low level of automation of rare earth molten salt electrolysis process, this paper proposes to study the intelligent control system of rare earth molten salt electrolysis. The overall framework of the intelligent control system is constructed, and the key technologies of the intelligent control system are studied. The fuzzy self-adaptive PID control algorithm is proposed to realize the real-time adjustment of molten salt temperature of electrolytic cell by coordinating the control of the discharge amount and the electrolytic power supply. The researched intelligent control system was tested in a 6 kA molten salt electrolyzer. The experimental results show that the intelligent control system can adaptively adjust the temperature of the electrolyzer, so that the temperature deviation is within ±0.9%, and the system performance is stable and practical. The study provides a certain technical guidance for the realization of the intelligent management of the rare earth molten salt electrolysis process.
