A Demonstration Experiment on Stochastic Fluctuation for a Conjecture on the Control Performance Improvements

Abstract

In this paper, the theoretical fact that Random fluctuations in feedback control scheme can improve its control performance is verified by using a practical demonstration experiment for a seesaw and cart control equipment. Unstable closed-loop system with a simple proportional control law is stabilized due to the state-dependent fluctuation. Our theoretical expectation on the control performance improvements due to fluctuation are shown from both aspects of numerical simulations and its experimental validation.
