【英文篇名】 Application of self-adaptive fuzzy control technique to central air conditioning systems 【作者中文名】 周竹; 李群湛; 霍继明; 【作者英文名】 By Zhou Zhu; Li Qunzhan and Huo Jiming Southwest Jiaotong University; Chengdu; China; 【作者单位】 西南交通大学; 深圳南瑞科技有限公司; 【文献出处】 暖通空调, Heating Ventilating 模糊控制; 集中空调系统; 控制规则集; 控制策略; 【英文关键词】 self-adaptive control; fuzzy control; central air conditioning system; control rule set; control strategy; 【摘要】 将自适应模糊控制技术引入到集中空调PID控制系统中,以提高系统的控制精度、稳定性和其他性能。引入温湿度参考模型,构造了模糊自适应机构,实现了在线修改模糊控制系统规则库。采用三角型隶属度函数、最小值推理法和加权平均法简化了模糊推理过程。给出了自适应模糊控制技术的控制规则集、知识库修正方法和控制策略,并进行了系统仿真研究和性能分析。 【英文摘要】 Introduces the self-adaptive fuzzy control technique to the PID control system of a central air conditioning system in order to improve the control precision, stability and other performance. Constructs the fuzzy self-adaptive organization by involving a temperature-humidity reference model, which can modify the rules of fuzzy controller on line. Adopts the triangle membership function, minimum inference method and weighted average method to simplify the fuzzy inference process. Provides the control rule se...
