In this paper,the boundary stabilization problem of an axially moving tape system is considered.The tape moves between two sets of rollers,where the right roller is fixed and the left roller,with its mass taken into account,is free to move,rotate,and subject to external disturbances.The active disturbance rejection control approach is adopted in the investigation.First,extended state observers are designed to estimate the disturbances,and then,feedback controllers are proposed to cancel the effect of the disturbances.The well-posedness of the closed-loop system is proved by the semigroup theory.Furthermore,the exponential stability is achieved by constructing a suitable Lyapunov function.Finally,numerical simulations are given to support these results. 展开更多
