摘要
针对日益复杂的楼宇中央空调的监控要求,分析了楼宇中央空调控制系统的干扰因素,并重点阐述了空调湿度控制系统的特点。实验表明空调湿度控制系统具有一定的时变时滞特性,控制策略使用了鲁棒数字PII。该策略的主要控制思想是:"小"比例和积分控制实现时变时滞的鲁棒调节控制、修正积分控制抑制定值负载干扰。监控部分采用小型集散控制系统,并详细介绍了该监控系统的组成方案及仪表选型,最后简述了该监控方案的运行效果和节能效果。
The disturbing factors of central air-conditioner control system in the office building are studied for the increasing complicated requirements of monitored control central air-conditioner. The characteristics of air-conditioner humidity monitoring system are emphasized. The experiments show that the air-conditioner humidity monitor system has the properties of time varying and time delay. Robust digital PII is applied in monitor strategy. The'little' proportion + time varying and time delay robust adjusting monitor is controlled by integral, and the fixed value loading interference is restrained by adjusting integral monitor. Mini-typed distributed control system is adopted in monitor section. Composing scheme of this monitor system and selecting meters are introduced in detailed. The function and saving-energy effects of this scheme are also summarized.
