Port-Based Asymptotic Curve Tracking for Mechanical Systems

摘要

We examine the control problem of curve-tracking for a fully actuated mechanical system. Using a coordinate transformation on the momentum variables, we split the kinetic energy of the system in a desired and an undesired part, and then design an (intrinsically passive) controller as an interconnection of port-Hamiltonian subsystems, in such a way that asymptotic convergence to the desired curve is obtained. We illustrate the performance in a simulation.
