控制系统数据挑选问题的研究，针对气调减压绿色保鲜控制系统中由于各方面原因引起的采集信号畸变，采取模糊控制原理，设计模糊控制器，实现现场采集数据的挑选。对工作在环境相对恶劣的控制系统，有很好的借鉴作用。 -Control system for the selection of the study data, in view of fresh green decompression atmosphere control system caused as a result of various aspects of the acquisition signal distortion, to take the principle of fuzzy control, fuzzy controller design to realize the selection of scene data collection. Working in the environmental control system is relatively poor, have a good reference.
