Application of self-adaptive fuzzy control technique to central air conditioning systems
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。
Abstract：
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 sets, methods of revising knowledge base and control strategies and carries on simulation research and performance analysis for the system.
