Abstract：In order to address the challenges posed by the unwieldy regulation of air volume,the un-timeliness of regulation,and the deficiency in regulation accuracy in the wind location beneath the mine,this study proposes an intelligent mine louver regulation and control method within the venti-lation network for on-demand wind supply.The proposed method involves the construction of an automatic louver regulation and control system,the execution of experimental research,the pro-cessing of data through Kalman filtering,the establishment of a system mathematical model,and the development of a model.The subsequent step involves identifying,designing,and improving a PID controller for the automatic regulation of the louver,considering its characteristics.The regula-tion effects of PID control,fuzzy PID control,and segmented PID control are then compared.The next stage involves developing a remote monitoring software module for louver regulation,which is equipped with wind demand prediction and branch prioritization functions.Finally,the improved PID-based remote monitoring software module for louver regulation is applied in practice.PID con-trol,fuzzy PID control and segmented PID control of the regulation of the louver,the development of air demand prediction and branch preference function of the regulation of the remote monitoring software module of the louver,and improve the PID of the mine louver regulation and control sys-tem combined with the ventilation network real-time solving platform for use.The results show that:This paper has determined that the opening degree of the louver[0,35)is the high-sensitivity zone,[35,60)is the medium-sensitivity zone,and[60,90]is the low-sensitivity zone.The mathematical model of the louver automatic control and air regulation is obtained by system identifi-cation,and the transfer function model of the automatic louver control system is obtained.The fuzzy PID and segmented PID control algorithms are proposed.The control capabilities of the lou-ver are compared among PID,fuzzy PID,and segmented PID algorithms.The overshoots are 10.12%,13.36%,and 7.44%respectively,and the regulation times are 56.69,38.17,and 53.19 s respectively.The segmented PID algorithm has a smaller overshoot and can meet the re-quirements of stable air volume control.Combined with the improved PID mine louver control sys-tem and the real-time ventilation network solution platform,the louver opening degree is adjusted from 40° to 45° in the 23204 mining face.The air volume of the working face increases by 4.354 m3/s,and the air volume control of the working face and its related branches is achieved.
