Abstract: Tensile force and speed are a pair of strong coupling controlled variables. It is vital to decrease the speed change caused by the change of tensile force in the tension servo system. This paper employed an analysis approach to construct the mathematical model of the two-motor tension servo control system. It designed a PID controller based on BP neural network to carry on the adaptive decoupling control for the speed and tension variable in the system. The simulation results showed that compared with the traditional PID constant parameters control,the designed control system could obtain optimal parameters of the PID controller according to environmental change, realize better decoupling control of speed and tension, and possess great dynamic and static characteristics and good robustness.
Key words: neural network; tension servo system; decoupling control; speed; belt tension
