可控环境专家控制初探 李迎霞 杜尚丰 中国农业大学 电子信息系 北京 摘要 可控环境作用对象之一是生命科学中研究的作物，由于目前有关作物生长的信息、气候信息和土壤信 息的缺乏，通常把该系统称为复杂系统。在数值控制该类系统的基础上，把该系统丰富的启发式控制逻辑 进行组织，与传统的数值控制相结合，提出可控环境-温室环境的智能控制方法-专家控制。给出了知识库的 组成、构造方法和推理机制。 关键词 可控环境，复杂系统，环境模型，作物模型，专家控制 Research on Expert Control of Controlled Environment Li Yingxia Du Shangfeng Department of Electronic Information , China Agricultural University,Beijing 100083 Abstract One of studied objects in controlled environments is crops in life science researches which belong to complex systems. It is difficult to control these complex systems due to little information of crop growth models, climate models and soil models. While there are a lot of heuristic logic knowledge that is not used. So the expert control scheme is proposed in controlled environments by using heuristic logic knowledge to numerical control. Finally, the knowledge base structure and reasoning method are presented. Key words Controlled environment, complex system, environment model, crop model, expert control 1 引言 温室环境是可控环境，属于复杂系统，涉及作物（有生命的系统）与环境，传统的控制
