摘要
制氢系统的自动化控制对于设备的安全稳定运行和产品质量控制具有重要意义。热电阻炉加热系统是一个具有大惯性、纯滞后、分布参数非线性的系统,采用混合模糊PID控制算法控制电阻炉,既具有模糊控制快速、鲁棒性强的优点,又具有PID稳态精度高的优点。选用西门子公司的S7—300PLC实现控制功能,得到了比较好的控制效果。
Automatic control of a hydrogen production system is quite significant for the safety and stability of a device and product quality control. A resistance furnace is a large inertia, pure time delay and nonlinear distributed parameter system. It employs Fuzzy-PID algorithm to control temperature. The algorithm has such positive characteristics as flexibility, strong robustness and high stability precision. We select Siemens S7--300 PLC to achieve these characteristics and the control effects are desirable.
