摘　　要：为了获得满意的建筑采暖热舒适,并同时降低维持建筑热舒适的采暖经济成本,针对分户控制和热计量绿色建筑,提出了一种基于经济模型预测控制(EMPC)的节能热舒适预测控制策略.为此首先建立了采暖房间的非线性热舒适模型.采用近似方法,得到实用的非线性热舒适预测模型.构造了节能热舒适经济性能函数和优化问题来实现动态过程经济性能最优,得到了节能热舒适模型预测控制策略(EETCMPC).最后通过模拟仿真,与双层经济性能优化模型预测控制策略(DMPC)进行了比较分析.仿真结果表明,采用EETCMPC时,散热器辐射热量减少了,具有8.9%的节能效果.因此,该方法在分户热计量建筑采暖控制中切实可行,在获取满意的热舒适时,采暖房间的用热经济性能得到了提升,具有工程指导意义.In order to obtain satisfactory thermal comfort and reduce the economic cost of maintaining the thermal comfort of residential building,an energy-saving thermal comfort control strategy based on economic model predictive control(EMPC)is presented for green residential buildings which adopts household heat metering.Firstly,the nonlinear thermal comfort model of heating room is established.A practical nonlinear thermal comfort prediction model is obtained by using approximate method.Secondly,the cost function and optimization problem of energy-saving thermal comfort are constructed to realize the optimal economic performance of the dynamic process.The energy efficient thermal comfort MPC(EETCMPC) is designed.Finally,the EETCMPC and Double-layer MPC strategy(DMPC) are compared and analyzed by simulation.The simulation results show that the radiant heat of radiator is reduced when adopting EETCMPC,with an energy efficient of 8.9%.Therefore,this method is feasible in the heating control of household heat metering buildings.When obtaining satisfactory thermal comfort,the thermal economic performance of heating rooms is improved,which is significant for engineering application.
