摘　　要：文章针对高层建筑中央空调变风量自动控制中的超调量过大与不稳定问题,开展基于模糊PID控制策略的研究。通过构建基于模糊PID的变风量空调数学模型,实现对空调动态特性的精确描述。设计模糊PID控制器,利用模糊逻辑对PID控制参数进行在线调节,以适应不同工况下的控制需求;采用输入变量的隶属度函数计算方法,优化模糊控制规则,实现变风量空调的智能自动控制。通过对比试验证明:采用模糊PID控制策略的系统在响应速度、控制精度和稳定性方面均优于现有控制方法,有效提高了高层建筑中央空调的能效和舒适度。Aiming at the problem of excessive overshoot and instability in the automatic control of variable air volume of central air conditioning in high-rise buildings,this article studies the control strategy based on Fuzzy PID.By constructing the mathematical model of VAV air conditioning based on Fuzzy PID,the accurate description of the dynamic characteristics of air conditioning is realized.The fuzzy PID controller is designed,and the fuzzy logic is used to adjust the PID control parameters online to meet the control requirements under different working conditions;The membership function calculation method of input variables is used to optimize the fuzzy control rules and realize the intelligent automatic control of VAV air conditioning.Through comparative experiments,it is proved that the system using fuzzy PID control strategy is superior to the existing control methods in response speed,control accuracy and stability,and effectively improves the energy efficiency and comfort of central air conditioning in high-rise buildings.
