摘要
基于智能建筑环境技术试验平台,分析了变风量空调系统的风管静压控制,对采集的数据使用最小二乘的系统辨识方法建立静压控制回路模型,并采用变速积分算法和Z-N整定算法对传递函数进行控制,对比得到一组较优的PID参数。
Based on a test platform of intelligent building environment, this paper analyzed the static pressure control of wind tube in variable air volume air-conditioning system. By using the least squares system identification method to dispose the collected data, then the static pressure control loop model was established. The variable integral algorithm and Z-N tuning algorithm controlled the transfer function, and a set of the optimal PID parameters are obtained.
