Research on fuzzy neural network control method for high-frequency vacuum drying of wood

高频真空木材干燥是一种干燥速度快、能源消耗低、环境污染小的新型联合干燥技术。在木材高频真空联合干燥过程的理论分析基础上,针对神经网络方法建立的木材干燥模型,设计了木材干燥模糊控制器和模糊神经网络控制器。对模糊控制和模糊神经网络两种控制方法进行了仿真实验,结果表明模糊神经网络方法控制效果更好,如温度上升快,控制精度高,稳定性好。模糊神经网络控制方法对实现木材干燥过程的全自动控制具有重要研究意义。

High-frequency vacuum combined wood drying is a kind of fast drying speed, low energy consumption,little environmental pollution of new drying technology. On the basis of theoretical analysis with high frequency in wood vacuum drying process,the fuzzy contro-ller and fuzzy neural network controller of wood drying are designed in view of the neural net-work method to establish model of wood drying. The simulation experiment results show that fuzzy neural network control is better,such as the temperature rising fast,high control preci-sion,good stability. The method to realize the automatic control of timber drying process has important research significance.
