摘要
本文主要探究了自适应模糊PID控制技术在办公建筑变流量中央空调冷冻水系统中的应用效果。文章首先介绍了中央空调冷冻水系统的控制原理,分析了常规PID控制原理,并通过Matlab仿真软件中的Simulink模块创建了常规PID控制器的仿真模型,设定参数后进行仿真控制。结果表明,冷冻水系统虽然能达到控制目标,但是存在超调量较大、调节用时偏长等问题。随后提出了一种基于自适应模糊PID控制器的冷冻水系统优化控制技术,同样进行了仿真实验。对比可以发现,优化后的冷冻水系统超调量更小,响应速度更快,优化效果明显。
This paper mainly explores the application effect of adaptive fuzzy PID control technology in the chilled water system of variable flow central air conditioning in office buildings.This paper first introduces the control principle of the central air conditioning chilled water system,analyzes the conventional PID control principle,and establishes the simulation model of the conventional PID controller through the Simulink module of Matlab simulation software,and then carries on the simulation control after setting parameters.The results show that although the chilled water system can achieve the control goal,there are some problems such as large overshoot and long adjustment time.Then,an optimized control technology of chilled water system based on adaptive fuzzy PID controller is proposed,and simulation experiments are also carried out.The comparison shows that the optimized chilled water system has smaller overshoot,faster response speed and obvious optimization effect.
