With this choice, the closed-loop potential energy contains free functions of the new variables. By expressing the regulation objective in terms of these new potential shape variables, the desired equilibrium can be assigned and there is freedom to reshape the potential energy to achieve performance whilst maintaining the PHS form in closed loop. This complements contemporary results in the literature, which preserve the open-loop shape variables. As a case study, we consider a robotic manipulator mounted on a flexible base and compensate for the motion of the base while positioning the end effector with respect to the ground reference. We compare the proposed control strategy with special cases that correspond to other energy shaping strategies previously proposed in the literature.]]> Sat 24 Mar 2018 07:53:00 AEDT ]]> Robust speed tracking control of synchronous motors using immersion and invariance https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25764 Sat 24 Mar 2018 07:30:52 AEDT ]]>
