基于PLC模糊控制的列车制动软管试验台的设计与应用

摘要

According to the instability station of manually load of the train braking tube experimental station, the manual loading valve was transformed into digital valve by using stepper motor. By the way of combining fuzzy control and PLC, the automatic control system of the experimental station was designed. The practical application indicates that the control system is stable, reliable and pre-cise.%根据列车制动软管试验台手动加载不稳定的情况,利用步进电机把手动加载阀改造成数字阀,采用模糊控制与PLC相结合的方式,设计试验台自动控制系统.实际应用结果表明:该控制系统具有稳定可靠、控制精确的特点.
