摘　　要：提出基于动态矩阵控制算法(DMC算法)的室内温度控制方法。将DMC算法联合TRNSYS软件建立散热器室内供暖系统仿真模型,对室内温度控制效果影响因素(用户调节阀流量特性、供暖时期、供水温度)进行分析。比较DMC算法、PID控制、预测-反馈预测控制对室内温度的控制效果。DMC算法具有比较强的鲁棒性。与PID控制相比,DMC算法对室内温度的控制效果更佳。预测-反馈预测控制对室内温度的控制效果略优于DMC算法,但效果有限。A room temperature control method based on dynamic matrix control(DMC)algorithm is proposed.By combining the DMC algorithm with TRNSYS software,a simulation model of radiator indoor heating system is established,and the influencing factors of room temperature control effect(flow characteristics of user control valve,heating period and water supply temperature)are analyzed.The control effects of DMC algorithm,PID control and prediction-feedback predictive control on room temperature are compared.The DMC algorithm has strong robustness.Compared with PID control,DMC algorithm has better control effect on room temperature.The prediction-feedback predictive control has a slightly better control effect on indoor temperature than the DMC algorithm,but the effect is limited.
