Application of Feed-Forward and Feedback Control in Tensile Controller

Abstract

According to the disturbance of speed changing in the tension, in order to overcome the speed change for the influence of the system tension control, a tension controller based on the Proportion Integration Differentiation feedback control additionally the feed-forward compensation is designed. The control principle of system, hardware control system and the program design are introduced, the hardware control circuit is mainly composed of digital signal processing. The controller has the advantages of fast speed response, smooth adjustment, Strong disturbance ability, etc. The actual application proved the design is correct and effective.
