Local fan can provide fresh air for mine roadway excavation and production,regulate gas concentration and ensure operation safety.The local fan control system has the characteristics of pure hysteresis,nonlinear,multi-disturbance,etc.The traditional PID control method is difficult to achieve the ideal control effect.In this paper,an intelligent control system,fuzzy control,is proposed and applied.The practice shows that the improved fuzzy controller can adjust the gas concentration according to the driving face,ensure the safety of underground working environment,and the energy saving effect is remarkable.
