Abstract

This paper presents a hybrid model predictive control (MPC) scheme for energy-saving control in commercial buildings. The proposed method combines a linear MPC with a neural network feedback linearisation (NNFL) method. The control model for the linear MPC is developed using a simplified physical model, while nonlinearities associated with the building system are handled by an affine recurrent neural network (ARNN) model through system feedback. The proposed MPC integrates several advanced air-conditioning control strategies, such as an economizer control, an optimal start-stop control, and a pre-cooling control. The developed MPC has been tested in the check-in hall of T-1 building, Adelaide Airport, through both simulation and field experiment. The result shows that the proposed control scheme can achieve a considerable amount of savings without violating occupants' thermal comfort.
一种用于商业建筑节能降耗的混合模型预测控制方案:仿真与实验
提出了一种用于商业建筑节能控制的混合模型预测控制(MPC)方案。该方法结合了线性MPC和神经网络反馈线性化(NNFL)方法。采用简化的物理模型建立了线性MPC的控制模型,而通过系统反馈,采用仿射递归神经网络(ARNN)模型处理与建筑系统相关的非线性。提出的MPC集成了几种先进的空调控制策略,如省煤器控制、最优启停控制和预冷控制。所开发的MPC已在阿德莱德机场T-1大楼值机大厅进行了仿真和现场试验。结果表明,所提出的控制方案可以在不影响乘员热舒适的情况下实现大量的节能。
