【摘要】 煤矿的开采过程中，矿井的局部通风系统对工作面的安全具有重要的作用。随着煤矿开采深度的不断增加，局部通风机的风量动态调节是保证煤矿安全开采的重要因素。由于矿井通风系统的复杂性及非线性特征，采用PID控制与模糊控制相结合的方式进行局部通风机的自适应模糊PID控制。通过Simulink仿真分析可知，自适应模糊PID控制系统在局部通风机的风量调节中能够较快地达到系统的稳定，并减小超调量15%，实现较好的调节效果。更多还原

【Abstract】 In the mining process of coal mines, the local ventilation system of the mine plays an important role in the safety of the working face. With the increasing mining depth of coal mines, the dynamic adjustment of the air flow of local ventilation fans is an important factor to ensure the safe mining of coal mines. Due to the complexity and non-linear characteristics of the mine ventilation system, a combination of PID control and fuzzy control is used for adaptive fuzzy PID control of the local ventilation fan. The Simulink simulation shows that the adaptive fuzzy PID control system is able to stabilize the system faster and reduce the overshoot by 15% in the local ventilation fan airflow regulation, achieving a better regulation effect.更多还原
