✦ Synopsis

A pendulum whose support is subjected to a periodic non-harmonic oscillation in the vertical direction is considered. The subharmonic Melnikov functions for the oscillating and for the rotating motions are explicitly constructed. It is shown that both functions converge towards the homoclinic Melnikov function and furthermore all the results for the harmonic perturbation are recovered.

In this paper, the e!ect of a vibrating support base upon the behavior of a simple robotic manipulator with PD control is examined. The physical system to be controlled, i.e., the plant, is modelled initially as an inverted pendulum. The vibrating support generates a time-periodic parametric excitat
