Abstract
This article presents a decentralized tension controller for large-scale roll-to-roll machines under the consideration of inherent nonlinearity and parameter variations. First, active-damping injection with specific proportional-integral gain is adopted to render the first-order dynamics for the closed-loop system via stable pole- zero cancelation. Second, the nonlinear disturbance observers for each loop intensify the high-frequency disturbance attenuation capability with a combination of regulation error integral actions. Moreover, the closed-loop analysis results include the proof of performance recovery from the first and second features. Various simulation results validate the effectiveness of the proposed technique from a combination of active-damping and DOBs using MATLAB/Simulink.
