摘　　要：基于能量守恒定律和集总热容法分析和建立了集中供热系统数学模型,利用组态软件编制仿真程序,采用常规PID控制器和气候补偿改进算法两种控制策略分别对供热系统进行仿真.结果表明,气候补偿策略可有效解决常规PID控制方式在气温波动干扰下易出现的热量供需不平衡问题,对供热系统研究和设计具有一定的参考价值.Based on the law of conservation of energy and the lumped heat capacity,a mathematical model of central heating system was analyzed and established.A simulation program was developed to simulate the dynamic process of the system under temperature disturbance.Two control strategies,the conventional PID control and the improved climate compensation control,were used to simulate the heating system respectively.The results showed that the improved strategy based on the climate compensation can effectively solve the problem that the conventional PID control strategy was prone to heat supply and demand imbalance under the interference of temperature fluctuations.It has certain reference value for the research and design of heating system.
