粒子群算法在武汉市图书馆变风量空调控制系统中的应用研究

摘要

以武汉市图书馆公共建筑节能项目为背景，考虑到现有的方法有如下缺点：系统惯性大、时间滞后及单一采用PID 控制时，控制效果不好，我们找寻到了一种高效的方法来解决这些缺点，实现优化温度参量来控制。根据变风量空调系统的结构，对变风量系统室内温度控制环节采用粒子群算法，经过 Matlab 软件进行仿真，使室内温度控制环节的上升时间、超调量及调整时间得以优化。%This work is based on the library of wuhan public building energy efficiency project ,thinking about the exi‐ting methods have disadvantage ,including system inertia inefficiently ,time delay and the control performance unsatisfactorily with single PID controller .An efficient method is proposed to overcome the disadvantages .The method optimized the time parameters ,based on the construct of VAV(Variable Air Volume) system using PSO(Particle Swarm Optimization) to con‐trol the indoor temperature .The method is simulated by Matlab and the result demostrates that our work is optimized on ri‐setime ,overshoot and debug time .
