Abstract This paper investigates the asymptotical stabilization of port-controlled Hamiltonian (PCH) systems via the improved potential energy-shaping (IPES) method. First, a desired potential energy introduced by a transitive Hamiltonian function is added to the original kinetic energy to yield a desired Hamiltonian function. Second, an asymptotically stabilized controller is designed based on a new matching equation with the obtained Hamiltonian function. Finally, a numerical example is given to show the effectiveness of the proposed method. Ausführliche Beschreibung
