摘　　要：由于传统PID控制本质上是一种线性控制,其自适应性及鲁棒性相对较差,不能实现高性能的控制。为了改善系统的控制品质,针对矿井供风量的非线性,时变及滞后的特点,提出将基于PLC的模糊控制方法应用于矿井供风系统中,利用模糊控制对变频恒压供风系统进行了改进研究。The traditional PID control with relatively meager adaptability and robustness is a kind of linear control in effect , and fail to fulfill induction motor drive with high quality. In order to improve control effect of system, this paper aimes at the characteristic of the aerate of mine nonlinear, time - varying and time - lagging, proposes applying fuzzy control based on PLC to the control of the aerate system of mine, and improves the aerate system using fuzzy control.
