摘　　要：针对矿井掘进工作面巷道的长度、风阻、瓦斯的浓度等诸多因素的不确定性,以局部通风机为研究对象,设计出结合PI控制和模糊控制的双模控制器,有效地解决了单一控制算法下动态性能和稳态误差之间的矛盾。通过建模仿真表明,模糊-PI双模控制融合了2种不同控制算法的优势,实时控制通风机的转速随矿井的通风量及瓦斯浓度变化,具有较小的超调量和较高的稳态精度。According to the length of roadway,wind resistance,the concentration of gas and many other factors of uncertainty in the mine heading face,a dual-mode controller is proposed which realizes the combination of fuzzy control and traditional PI control with the study of local fans to solve the main conflict of the dynamic performance with the steady-state error effectively adopting a single control algorithm.Modeling and simulation results show that the dual-mode fuzzy-PI control algorithm merges the advantages of both control algorithm,can control speed of the fan with the mine ventilation and gas concentration change in real time and has quick response speed,high steady accuracy.
