摘要
针对目前物料微波干燥过程中温度和湿度存在耦合关系导致执行机构工作稳定性差、干燥能耗大、效率低、烘干不均匀等问题,采用补偿模糊解耦算法,设计了干燥过程温湿度控制系统,分析并选择了温度、湿度、水分传感器、数据采集板等主要器件。该系统运行可靠,能实时监测干燥过程中的温度和湿度等参数,实现了干燥过程中温湿度精确控制,提高了物料干燥过程控制的智能化程度,简化干燥过程操作及数据处理。
According to the temperature and humidity coupling phenomena in the proeess of mierowave drying, by using the controlling technology of compensated fuzzy deeoupling, the temperate and humidity control system for microwave drying process is designed to realize their real-time test and automatie control. The temperate sensors, humidity sensors, moisture sensors and acquiring-data block are selected. Experiment studies were carried out. The experimental results show that the fuzzy controller has the features of quick response, small over-shoot, accurate action and steady process to meet the requirement of drying technology of grain.The control of temperate and humidity is very well.
