基于PMV指标的列车空调模糊控制研究

Research on the fuzzy control of train air-conditioning based on PMV index

采用热舒适控制不仅能满足人体的舒适感,而且还能满足系统节能的需要.对热舒适控制中的各变量进行了分析,采用模糊控制技术,选择空气温度作为直接受控的参数,并通过调节送风量来实现.以车厢内PMV值的偏差及偏差变化率作为模糊控制器的输入,进行新风量的合理控制,使列车空调的控制随着人体舒适感的变化而变化.

The thermal comfort control was applied to meet the need of comfortable feeling of people and meet the demands of system energy saving. It was analyzed the variables in the thermal comfort control in train airconditioning by fuzzy control technique and get the air temperature as the parameter by directly control. PMV value deviation in the vehicle and deviation variety rate were proved to be important in fuzzy controller with reasonable control of the fresh air volume, and control of the train air-conditioning changed in pace with the human variety of thermal comfort.
