本文提出了一种基于推理模型的预测控制方案，可以对多区域供热系统中的锅炉进行优化控制，以达到节能和改善热舒适性的目的。控制器只有三个输入：外部空气温度的测量，落在建筑物外部的总太阳辐射的估计，以及由锅炉供应的水的温度的测量，以及一个输出：锅炉控制信号。该模型的参数是从使用便携式温度记录仪收集的输入输出数据估计的，便携式温度记录仪临时安装在建筑物中，以在一两周的短暂调试期间监测室温。在不同的供热系统的控制方案的性能进行了研究，使用供热系统模拟器，这已经开发和验证在以前的项目。仿真结果表明，与传统的锅炉控制方案相比，该控制方案能显著提高供热系统的整体性能，且易于调试。控制器在真实的建筑物的实验评估的结果也被提出。
An inferential model-based predictive control scheme is described that can optimize the control of boilers in multi-zone heating systems in order to save energy and to improve thermal comfort. The controller has only three inputs: a measurement of the outside air temperature, an estimate of the total solar radiation falling on the exterior of the building, and a measurement of the temperature of the water being supplied by the boiler, and one output: the boiler control signal. The parameters of the model are estimated from input-output data collected using portable temperature loggers, which are temporarily installed in the building to monitor the room temperatures during a short commissioning period of one or two weeks. The performance of the control scheme in different heating systems is investigated using a heating system simulator, which had been developed and validated in previous projects. The simulation results show that the control scheme can significantly improve the overall performance of heating systems compared with conventional boiler control schemes and is easy to commission. The results of an experimental evaluation of the controller in a real building are also presented.
