| 摘 要： | 目前茶叶用烘干机的燃煤热风炉存在能耗高、热效率低的问题,而且大多采用人工控制,温度稳定性差,品质也难以保证。为此,采用模糊控制技术对热风温度进行恒温控制,根据热风炉热风温度的高低,通过变频器自动调节热风炉的排烟量,控制热风温度达到恒定,在满足烘干需要的同时,减小能量损耗,保证茶叶品质。同时,应用MATLAB软件对模糊PID恒温控制系统进行仿真。结果表明,该系统可以有效控制热风温度,达到恒温控制的目的。

| Abstract: | The tea with a coal stove drying machine has high energy consumption, low thermal efficiency problems, mostly adopts manual control, causes the tea drying temperature is not stable, and effect of tea quality stability. Therefore, by using fuzzy control technology to control the temperature of hot air, according to the temperature of hot air from blast furnace, flue gas quantity is adjusted automatically through the inverter, to control hot temperature reaches a constant, to meet the need of drying at the same time, reduce the energy consumption, and ensure the quality of tea. Finally, the of fuzzy PID temperature control system is simulated by of MATLAB software, the results show that the system can effectively control the temperature of hot air, the temperature control of the objective. |
