Abstract :
This paper deals with the application of passivity theory to analyze the asymptotic stability of output feedback regulators for elastic joint robots paying attention to energy shaping based controllers. To this end we use a theorem which is an adaptation, for asymptotic stability purposes, of a passivity theorem given by Khalil (1996) and Canudas de Wit et al. (1996). This theorem is based on the works of Willems (1972) and Hill and Moylan (1977)
