摘要
焊锡炉具有大滞后、非线性、大惯性等特性,这给模型辨识带来了难度。该文以焊锡炉为研究对象,简单介绍其结构与温升特性,提出一种基于继电器反馈的建模法。通过与阶跃响应面积法相比较,可以看出该算法更具合理性,对焊锡炉温升过程曲线的依赖性小。实验结果证实了方法的有效性。
Solder furnace has a large delay,nonlinear,large inertia and other characteristics,which brings difficulty to the model identification.Solder furnace is taken as the research object in this paper.A modeling method based on relay feedback has been proposed after the description of soler furnace structure and temperature characteristics.Compared with the step response area method,the algorithm is more reasonable.The method needs less informaiton about the solder temperature rise curves.Experimental results confirm the validity of the method.
