Inthispa鄄 per,according to the instability heat in the internal mine and the control model is not easy to get,thefuzzy PID controller is designed,and thefuzzyPIDcontrollerissimulatedbytheSimulinksoftware. Combinedwiththetechnologicalprocessof mine local cooling,the control system which has simple structure and stable performance is established with the application of the control plan of the S7-200PLCtouch screen,then experiment of simulating minetemperature environment inthelaboratory is operated. The results show that the dynamic and staticperformanceof fuzzy PIDcontroller is superior tothe conventional PID controller.
