Intelligent control system of local fan based on fuzzy control

LI Wenhua;LI Chunlei;YU Ning;School of Mechanical Engineering,Liaoning Technical University;  
An intelligent control system of local fan based on fuzzy control theory was designed in view of the defects of control system of local fan in conventional mines. The roadway parameters of temperature,gas concentration and the equivalent depth were introduced,the functional relationship of voltage of frequency converter and field temperature and gas concentration was established by fuzzy control theory,and the algorithm of voltage of frequency converter based on the influence of equivalent depth of roadway was established to realize the intelligent control of local fan by frequency control. Practical operating results show that the system can guarantee the ventilation safety of excavation roadway,save 36.8% of electricity consumption and maximize the efficiency of the local fan.
