摘要
针对目前微波木材干燥存在智能化程度低、干燥质量差和耗能多等缺点,分析了微波木材干燥的过程及其特点,考虑到温湿度控制的非线性、强时变特性,设计了一个可用于微波木材干燥窑的智能温湿度模糊控制器。在确定了控制器的模糊子集、隶属度函数及控制规则的基础上,搭建了Simulink平台,并利用SRO响应优化模块进行优化设计。仿真结果表明,设计的模糊控制器可实现对温湿度的快速和无超调控制,它对于提高微波木材干燥设备的智能化水平具有一定的意义。
Aiming at the demerits of existing microwave timber drying processes, i.e. , low level of intelligence, low quality and high energy consumption, etc. , the microwave drying process and its features are analyzed. Considering the nonlinear and time varying characteristics of the temperature and humidity control, the intelligent fuzzy controller used for microwave timber drying kiln has been designed. Firstly, the fuzzy subset, membership function and control rule of the controller are determined to setup Simulink platform. Then, the optimization design is carried out with Simulink response optimization module. The result of simulation indicates that fast speed and non-overshoot control of temperature and humidity can be implemented by using the fuzzy controller. The design is significant to enhance intelligent level for microwave timber drying equipment.
