✦ Synopsis

In this paper, we present a control strategy for an axially moving web system that regulates transverse vibration and ensures that the web speed tracks a desired trajectory. The control strategy is implemented using roller torque inputs applied at the boundary and a pair of control forces applied to the web via a mechanical guide. Given the hybrid model of the web system (i.e. the distributed parameter "eld equation coupled to discrete actuator equations), Lyapunov-type arguments are utilised to design a model-based control law that exponentially regulates the axial speed tracking error and the web displacement. The proposed control law is based on measurements of the web speed and displacement, slope, and slope rate at the mechanical guide. Experimental results demonstrate the speed tracking and vibration damping provided by the control strategy.
