摘　　要：利用自抗扰技术来控制矿井局部通风设备的风量调节,并根据矿井内的瓦斯浓度变化来不断调整输出风量,不仅能确保煤矿的生产安全,同时起到节约电能的效果。仿真结果表明,采用自抗扰技术控制矿井的风量排送系统,不需要控制对象具有精确的数学模型,且在多滞后、干扰大的风量控制系统中具有工作稳定、适应性强和抗扰能力强的特点。The self-disturbance rejection technology is used to control the air volume regulation of the mine local ventilation equipment,and the output air volume is constantly adjusted according to the change of gas concentration in the mine.It can not only ensure the production safety of the coal mine, but also save the electric energy,The simuIation results show that the control system of air volume delivery system using auto disturbance rejection technology does not need accurate mathematical model, and has the characteristics of stable work,strong adaptability and strong anti-interference ability in the air volume control system with large number of lag and large disturbance.
