Optimization control of air quantity supply during the switching process of mine ventilators
Zhang Shengliang
Abstract：The switching process of main ventilators in mine is an important link in safety production of mine.During this process,the operation of air duct switching damper may cause large-scale fluctuations in air supply,posing a threat to safety production of mine.Based on this,a dynamic model of switching process of ventilators was constructed,and optimization control objectives and constraints of model were determined.A method for optimizing air supply during the switching process of main ventilators was proposed.The air sup-ply controller was designed through PID control and optimized in practical applications.Simulation experiment analysis shows that the optimized method for controlling air supply during switching process of main ventilators can improve the total pressure of ventilator,meeting the requirements of mine ventilation system for ventilation stability.
