AI Technical Summary

Technical Problem

Existing water-gas reduction firing control technology for electric porcelain cannot achieve linkage sensing and decoupled control of multi-section atmosphere fields, resulting in spatiotemporal inhomogeneity of the reducing atmosphere, large temperature deviation, mutual interference of parameter adjustments, high energy consumption, and unstable product quality.

Method used

A control system based on an adaptive fuzzy PID algorithm is adopted. By generating a reduction potential trajectory through real-time data acquisition and adaptively updating the fuzzy PID algorithm, the air-fuel ratio and upstream micro-mixing are independently adjusted, reducing the complexity of the atmosphere state and improving control accuracy and stability.

Benefits of technology

It achieves precise control of the reduction firing process, reduces energy consumption, decreases defects, improves product consistency and electrical performance, and enhances production transparency and timeliness of decision-making.

Abstract

本发明涉及过程控制技术领域,具体公开基于自适应模糊PID算法的水煤气还原烧成电瓷控制系统,该系统通过设置实时还原轨迹耦合模块、还原烧成误差计算模块、执行层误差消除控制模块,先用感知层采集水煤气成分、空气与燃气流量、炉温、炉压、露点等主体数据,并按当前温度区间读取还原势标定权重,两者耦合生成实时还原势轨迹;再依据工艺设定生成目标还原势轨迹,两条轨迹比对得到还原烧成误差;决策层据此自适应更新模糊比例、积分、微分算法;同时计算空气侧前馈因子先行抵消可预见扰动;随后把剩余误差换算成两路控制量(空燃比修正量与上游微混修正量)下发到燃气比例阀和空气阀,实现稳定的水煤气还原烧成控制。
