PARAMETRIC-RESONANCE-BASED CONTROL OF BUOY CARDANIC SYSTEM FOR A BEACON SIGNALIZATION
This work aims at the control of nonlinear oscillations in a multibody dynamics composed by a moored buoy and a gimbal-beacon system that can swing like a physical pendulum restrained to a planar motion on a moving plane. We define a control objective based on parametric resonance on the pendulum employing a sliding mass in the underside of the rod. Additionally we analyze the mechanical energy transference on the pendulum oscillation due to buoy motions like tilts and yaw motion. The control performance in the presence of buoy-induced perturbations on the controlled oscillations stays as the main issue of the paper.
