Building Room Temperature Prediction and Control Based on Equivalent RC Model

传统室温控制存在滞后性大、鲁棒性弱等问题,通过TRNSYS仿真、热电类比、参数辨识建立目标建筑等效RC模型,基于闭环MPC方案和Simulink建立目标建筑室温模型预测控制仿真平台。对比相同模型在PID控制策略下的耗电量,验证了模型预测控制在建筑室温控制、节能减排上的优越性。

Traditional room temperature control has problems such as large hysteresis and weak robustness.The equivalent RC model of the target building is established through TRNSYS simulation,thermoelectric analogy,and parameter identification.Based on the closed-loop MPC scheme and Simulink,the target building room temperature model prediction control simulation platform is established,and the power consumption of the same model under the PID control strategy is compared.The superiority of model predictive control in building room temperature control,energy saving and emission reduction.
