Chaos Control Methods Applied to Avoid Bifurcations in Pendulum Dynamics

Abstract:

This paper deals with the application of chaos controlmethods in order to perform bifurcation control of a parametric pendulum-shaker system. The extended time-delayed feedback control method is employed to maintain stable rotational solution of the system avoiding bifurcation to chaos. The considered pendulum system is chosen due to its potential application for extracting energy from sea waves. This alternative concept of energy harvesting is based on exploiting the rotational unbounded solution of the pendulum dynamics. The bifurcation control proposed allows the system to keep the desired rotational solution over extended parameter range avoiding undesirable changes in system dynamics.
