摘　　要：热泵系统广泛应用于供暖领域,为了实现更高效的热泵系统控制,对空气能热泵测控系统进行了总体方案设计,引入了模糊控制与Smith预估补偿控制策略对PID进行优化;在信息系统设计中,采用了MQTT作为通信代理协议;经实验测试,当模糊PID控制器受到正弦干扰后,在510 s后才达到设定温度;而结合了Smith的模糊PID控制器在1250 s时跌至温度最低值,且其在260 s时便达到设定的温度值;经实际应用,设计的热泵测控系统在温度控制与系统运行方面均具有较强的鲁棒性与可行性,为现代热泵系统的智能化控制提供了一种有效的方法。Heat pump systems are widely used in the heating field.To efficiently control heat pump systems,an overall scheme is developed for the air energy heat pump measurement and control system.Fuzzy control and Smith predictive compensation control strategies are introduced to optimize the PID controller.In the information system design,The MQTT is used as the communication proxy protocol.Through experimental testing,the fuzzy PID controller reaches the set temperature after 510 s with the sinusoidal interference.However,the Smith based fuzzy PID controller reaches the lowest temperature value at 1250 s,reaching the set temperature value at 260 s.Through practical application,the designed heat pump measurement and control system has a strong robustness and feasibility in temperature control and system operation,providing an effective method for the intelligent control of modern heat pump systems.
