摘要
介绍了列车空调系统的自动化监测与节能模糊控制方案。列车空调系统是一个大的耗能系统,同时列车舒适节能是除了安全速度之外最关心的问题,对列车空调系统进行监测,并基于采集的数据采用模糊控制来调控空调系统的运行,就能达到节能并舒适的目标。系统对车厢温度、车厢空气湿度和CO2浓度这3个输入量进行模糊化处理,由控制规则推出输出模糊子集,再应用模糊推理合成规则得出控制输出量,控制器根据输出量来控制空调压缩机和通风扇的变频器运行以及启停电加热器的个数。
Energy saving and comfort request us to pay more attention to railway airconditions. By the electrical energy metering to the power and the realtime monitoring of the train, corresponding fuzzy control active measures were adopted to control the frequency converter of the power which supply the air condition to reduce energy consumption and provides fresh air. And the air conditions of the train were controlled to keep the coaches comfortable. It describes the fuzzy control strategy towards temperature, humidity and the carbon dioxide concentration of the air inside the coaches, including fuzziness of input, setting up of fuzzy control rules and certainty of outputs. The controlled objects are electrical motors which are droved by the optimal frequency converter.
