基于改进型模糊PID控制的空调水系统变流量调节优化节能研究

Research on Variable Flow Regulation and Energy Saving of Air Conditioning Water System Based on Improved Fuzzy PID Control

针对目前中央空调水系统控制参数自适应调节差和响应速度不够灵敏等诸多问题,提出了一种基于模糊自适应PID基础上的改进型模糊PID控制算法.此算法能在参数调节以及响应速度方面得到明显的提升;且通过将蚁群算法与模糊PID相结合,可以较好适应冷冻水系统的时变性,从而达到节能的目的.

In this paper, an improved fuzzy PID control algorithm based on fuzzy adaptive PID is proposed to solve the problems that the control parameters of the central air conditioning system are not adaptable and the response speed is not sensitive. This algorithm can improve the parameter adjustment and response speed. By combining the ant colony algorithm with the fuzzy PID, it can better adapt itself to the time-varying nature of the chilled water system, so as to achieve the goal of energy saving.
