TL;DR: In this article, an active vibration control of a translating tensioned beam with a varying traveling speed is presented. And the dynamics of beam and actuator are modeled via the extended Hamilton's principle.
Abstract: The investigational results for an active vibration control of a translating tensioned beam with a varying traveling speed are presented. The dynamics of beam and actuator is modeled via the extended Hamilton's principle. In a proper mathematical manner, the Lyapunov method is employed to design a boundary control law for ensuring the vibration reduction of the nonlinear time-varying system and also to ensure the exponential stability of the closed-loop system.

TL;DR: In this paper, a sliding mode observer is used to eliminate observation spillover in the vibration control of flexible structures, and the performance of the observer is compared with a conventional Kalman filter to demonstrate robustness and disturbance decoupling characteristics.
Abstract: The objective of this study is to demonstrate that sliding mode observers can eliminate observation spillover in the vibration control of flexible structures. It is common to build a state feedback controller and a state estimator based on the mathematical model of the system with a finite number of vibration modes, but this may cause control and observation spillover due to the residual (uncontrolled) modes. This paper deals with the elimination of observation spillover using a sliding mode observer. The performance of a sliding mode observer is compared with that of a conventional Kalman filter to demonstrate robustness and disturbance decoupling characteristics. Simulation and experimental results using the sliding mode observer are presented for active vibration control of a cantilever beam.
