基于逻辑模糊控制的农业专家系统（Agricultural expert system based on logical fuzzy control） Agricultural expert system based on logical fuzzy control Vegetable factory is mostly carried out in greenhouse production, or in makeshift shelter facilities, warm phosgene thermal environment for vegetable growth often changes due to external changes in the weather, as summer hot and dry, cold winter and weak light will become unfavorable factors affecting the growth of vegetable production, and factory production purpose is to maximize the environment relative controllability and adjustability, make vegetable plant growth in a relatively stable environment for, so as to maximize the production efficiency of the vegetable factory. Then the front also mentioned, diversity of environmental factors and the interaction of light, simply linear control is impossible, fuzzy logic reasoning and empirical must join the peoples formation, control model and program in accordance with the interval control, call control interval control is on the lower limit of the domain this value, for vegetable growth will not be affected, because the growth parameters of vegetables are applicable to a wide range, and more easily achieve the control interval is relatively reasonable and non conflict control of multi factors. For example, air temperature and air humidity control, often because of the high temperature in summer greenhouse cooling mist and must make the execution of the action will make the increase of humidity, if there is one point linear parameter control based on computer and control decision of ventilation dehumidifying, the exhaust fan will immediately open in this, frequent action in the process of implementation, not only can not achieve good control result, but also make use of the equipment pressure, greatly improve the rate of damage, unnecessary energy consumption naturally increases, the energy efficiency of vegetables is not consistent with the requirements of the factory. If each paramete
