Event-triggered model predictive control of building thermal environments
针对建筑室内热环境模型预测控制中的计算冗余和通信负担问题,提出了一种积分型事件触发控制策略.首先,考虑相邻热区温度的影响,基于等效电路法建立了一种简化的建筑电阻电容(resistance-capacitance,RC)热网络模型,并验证了模型的准确性;然后,提出了一种基于状态误差的积分型事件触发机制(integral-type event-triggered mechanism,ITETM),在此基础上,提出了基于 RC 热网络的积分型事件触发模型预测控制(model predictive control,MPC)方法;最后,通过EnergyPlus和MATLAB的联合仿真实验对所提出的控制方法性能进行验证.结果表明,所提出的控制策略可以有效减少优化问题的求解计算量和信息传输次数,并在保证室内温度舒适的同时降低建筑运行能耗.
To address the issues of computational redundancy and communication burden in model predictive control(MPC)of indoor thermal environments,this study proposes an integral-type event-triggered control strategy.First,a simplified building resistant-capacitance(RC)thermal network model is established using an equivalent circuit method,incorporating the influence of adjacent thermal zones,and its accuracy is verified.Then an integral-type event-triggered mechanism(ITETM)based on state errors is introduced.Building on this mechanism,an integral-type event-triggered MPC method grounded in the RC thermal network model is formulated.Finally,the performance of the proposed control method is verified by co-simulation experiments using EnergyPlus and MATLAB.The results show that the proposed control strategy effectively reduces computational effort and communication frequency in the optimization process,while lowering building energy consumption and maintaining indoor thermal comfort.
