【Abstract】 Within the field of fiber, paper making, plastic and metal plating, one of the key techniques to guarantee the product quality is for the control of winding tension of linear, strip and area materials. In this paper, the authors introduced a kind of artificial neural network with back-propagation training algorithm. This method overcame the shortcomings of the traditional PI control method, and effectively weakened the coupling action between the velocity and tension of the tension control system. Some simulation results indicated the favorable effect of the control algorithm.更多还原
