摘要
在烧结炉控制系统中,采用B型热电偶配合AD1674实现对烧结炉多点温度的采集,通过查表法达到非线性补偿的目的;控制系统采用C语言模块化编程;在温度控制方案上引入模糊控制算法。由Simulink仿真分析和系统实际运行情况可知:与传统PID算法相比,该算法的控制精度高,可达±0.1℃,系统的动态性能得到改善,鲁棒性增强。
B-type thermoeouple with AD1674 chip was used to realize multi-point temperature acquisition in the sintering furnace control system. The purpose of nonlinear compensation was achieved by the method of table-lookingup. C language was used as the module programming language. The Fuzzy-control methods were introduced in temperature control scheme. All of the merits are prove by the process of the simulation analysis based on Simulink and the practical operation： as compared with the traditional PID, the control precision of the fuzzy-control algorithm is increased up to± 0. 1℃ ; the robustness and the dynamic performance of the system are improved.
