Abstract
Based on linear active disturbance rejection control (LADRC) method, the control algorithm is designed for web tension regulation of self-developed LJF650A zero-speed splicer. The switching repeatedly working conditions and varying web length make the tension control of zero-speed splicer more difficult than the general web tension control. The LADRC design can actively estimate and compensate both the internal uncertain dynamics and external disturbances in real time. In this study, a realistic nonlinear model of zero-speed splicer for printing machine is deduced, and a fourth order linear extended state observer (LESO) is designed based on the simplified model of the accumulator. Simulations are presented and discussed for the LADRC controller, resulting with a better performance compared with decentralized PI controller.
