Résumé
Nonlinear vibration control is an area of growing interest in engineering. Geometric nonlinearities arise when vibration amplitudes become too large. While nonlinear vibrations have been controlled in the past, studies have never considered more than the first mode of vibration. This work aims to develop a novel dual-mode multi-input multi-output (MIMO) positive position feedback (PPF) controller. This controller was designed with two linear PPF filters, targeting the first and second natural modes, each in parallel with a cubic stiffness term. The controller was designed using SIMULINK and applied using piezoelectric actuator and sensor patches on a clamped sandwich beam, exhibiting hardening behaviour when excited by a stepped-sine excitation with increasing forcing levels. It was then compared to four other controllers: a SISO controller, a linear MIMO controller and two single-mode MIMO controllers, targeting the first and second modes respectively. The dual-mode MIMO PPF was shown to outperform the other four controllers in the control of the first two modes of vibration of the beam, making it the preferred option for such a purpose.
