Abstract
A new decoupling controller based on a unique active disturbance rejection control (ADRC) strategy is presented to strengthen tension stability in unwinding system of gravure printing machine. A nonlinear model is established according to the unwinding system working principle, and a decoupling model is constructed to determine the system order and static decoupling part. Then following the decoupling model, an ADRC decoupling controller is designed to enhance the tension stability in the unwinding system. Simulation shows that the proposed tension controller is able to realize a decoupling control for unwinding system and endowed with better internal robustness and disturbance rejection than traditional proportional-integral-derivative controller in tension control.
