Application of Controlled Lagrangian Method to Control a F lexible L ink

Controlled Lagrangian method is a branch of energy shaping methods designed to control underactuated mechanical systems. The method employs mechanical energy of a Lagrangian system as the Lyapunov function. This paper presents an application of controlled Lagrangian method to control a flexible link and exploit the results of the theoretical study in an experimental set-up. It is shown that the method’s performance is satisfactory from theoretical as well as empirical view point. Simulations and experiments validate the theoretical studies. Gains are tuned to attain good performance in the experimental study by regulating only one coefficient
