Abstract | We consider the undamped version of the shear beam model and design physically intuitive, stabilizing output feedbacks which employ distributed measurements of the beam and apply actuation only at the beam base. Our control design is a novel combination of the classical "damping boundary feedback" ideas with backstepping. The ``anti-collocated'' architecture that we pursue makes active control more readily implementable to several applications, including atomic force microscopy (AFM) where the piezo actuation is applied at the beam base. We also present an observer design dual to the damping feedback ideas. Finally numerical simulations are performed using the Chebyshev spectral method to show the performance of the control and the observer. | |
