Analytical and Numerical Analysis of Time-Delayed NDF Control for Nonlinear Rotating Pendulums with Stiffness Modulation Under Simultaneous Resonance Conditions

In this paper, the nonlinear dynamics and vibration suppression of a harmonically excited rotating pendulum are studied by a novel bidirectional coupled second-order auxiliary negative derivative feedback (NDF) controller. The governing equations are obtained by Lagrangian mechanics, extended to the case of quintic non...
