Fractional Euler-Lagrange modeling of a pendulum with a vertically vibrating pivot

This study develops classical and fractional variational models for a simple pendulum whose pivot undergoes prescribed vertical harmonic motion. The nonlinear classical equation of motion and its small-angle, Mathieu-type reduction are first derived from the Euler-Lagrange equati...
