摘　　要：目前国内外对风蚀风洞风速的控制精度和自动化程度不高,给实验室工作人员带来了很大的不便,而且风速易受外界不确定因素的影响,使实验数据的精度不够理想。以PLC为控制器,组建一套计算机操作指导控制系统,采用增量式模糊控制算法实现对风速的平稳控制,以达到提高试验精度和可靠性的目的,为我国的风蚀研究提供精确可靠的实验数据。At present precision and the automaticity for the wind speed of wind-erosion and wind-tunnel control is not too high home and abroad,and it has brought inconvenient for the laboratory staff.Moreover the wind speed influenced by the outside uncertainty element,it will causes the precision insufficiently for empirical datum,This article takes PLC as a controller,set up a set of computer-operation-instruction control system,uses the increase type fuzzy control algorithm to the wind speed control,and achieves the goal of enhancing experiment precision and the reliable. Providing the precise and reliable empirical datum for our country＇s wind erosion research.
