自适应PID控制在智能楼宇空调节能系统中的应用

The Application of Auto-Tune PID Control in Intelligent Building Air-Condition Energy-Saving System

智能楼宇自动化是建筑节能规划中非常重要的一部分,其中空调节能是楼宇节能系统的核心。空调节能控制是一个复杂的闭环控制系统,数学模型也比较复杂。在控制环节中,空调机组的功率特性、调温空间范围、外界热源的干扰以及空间内人员的分布和活动状态都会影响到精确数学模型的建立以及控制参数的设定。运用自适应PID控制技术,针对不同环境下的空调系统通过自动整定比例、积分、微分参数,以期达到最优化节能减排的效果;实践应用也证明运用的自适应PID控制技术是简单、高效、稳定、可靠的。

Intelligent building automation is a very important part of building energy-saving plan. Air conditioning energy efficiency is the core of the building energy saving system.A ir conditioning control is a complex closed-loop control system,and the mathematical model is also much complicated.In this con- trol point,there are many influences,such as the power of AHU,the scope of tempering space,the outside source of heat or cold,and the distribution and activity state of people.It used the auto-tune PID control technology aiming at auto-tuning proportional, integral, differential parameters of PID, and to optimize the energy saving effect in different situations.In application test,the effective and robust result can be got.
