供暖系统末端控制技术发展及研究综述
Development of terminal control technology for heating systems: A literature review
摘要：
结合我国供暖系统末端控制技术发展进程，分析了目前存在的主要问题，综述及评价了国内外末端控制相关研究情况。指出应针对散热器等具有较大热惯性和时滞性的供暖系统的特点，思考和探索新的具有预测功能的室温调控方法，并提出了突破单一用户室温控制、兼顾供暖系统水力工况及回水温度变化的系统优化控制思路。

Abstract：
Based on the terminal control technology development of heating systems in China, analyses the current main problems, and reviews the related research on terminal control at home and abroad. Points out that the predicted room temperature control method in view of radiators heating system with large thermal inertia and time lag should be exploded, and puts forward a system optimization control idea which breaks the single room temperature control mode and considers both hydraulic condition and return water temperature of the heating system.
Keywords:heating system, intelligent on-off control, model predicted control, hydraulic characteristic, return water temperature
