PD Control for Vibration Attenuation in a Physical Pendulum with Moving Mass

Abstract

This paper proposes a Proportional Derivative controller plus gravity compensation to damp out the oscillations of a frictionless physical pendulum with moving mass. A mass slides along the pendulum main axis and operates as an active vibration-damping element. The Lyapunov method together with the LaSalle’s theorem allows concluding closed-loop asymptotic… (More)
