AB - In the fiber winding process, strong disturbance, uncertainty, strong coupling, and fiber friction complicate the winding constant tension control. In order to effectively reduce the influence of these problems on the tension output, this paper proposed a tension fluctuation rejection strategy based on feedforward compensation. In addition to the bias harmonic curve of the unknown state, the tension fluctuation also contains the influence of bounded noise. A tension fluctuation observer (TFO) is designed to cancel the uncertain periodic signal, in which the frequency generator is used to estimate the critical parameter information. Then, the fluctuation signal is reconstructed by a third-order auxiliary filter. The estimated signal feedforward compensates for the actual tension fluctuation. Furthermore, a time-varying parameters fractional-order PID controller (TPFOPID) is realized to attenuate the bounded noise in the fluctuation. Finally, TPFOPID is enhanced by TFO and applied to control a tension control system considering multi-source disturbances. The stability of the method is analyzed by using the Lyapunov theorem. Finally, numerical simulations verify that the proposed scheme improves the tracking ability and robustness of the system in response to tension fluctuations.
