Brief paper: On the addition of integral action to port-controlled Hamiltonian systems
Alejandro Donaire,Sergio Junco +1 more
TL;DR: In this article, a new approach is applied to design speed regulation controllers for the permanent magnet synchronous motor and closed loop stability and asymptotic rejection of unknown piecewise constant load torques are formally proved.
Journal ArticleDOI
Passivity-based control for multi-vehicle systems subject to string constraints
TL;DR: In this paper, the authors show how heterogeneous bidirectional vehicle strings can be modelled as port-Hamiltonian systems, and propose a control law to guarantee string stability with respect to bounded disturbances.
Journal ArticleDOI
Robust energy shaping control of mechanical systems
TL;DR: In this article, it is shown that, if the inertia matrix is constant, constant disturbances (both, matched and unmatched) can be rejected simply adding a suitable integral action at the passive output.
Journal Article
Robust energy shaping control of mechanical systems
TL;DR: The problem of robustness improvement, vis a vis external disturbances, of energy shaping controllers for mechanical systems is addressed and it is shown that including a partial change of coordinates, the controller can be significantly simplified, preserving input-to-state stability with respect to matched disturbances.
Journal ArticleDOI
Shaping the Energy of Mechanical Systems Without Solving Partial Differential Equations
Alejandro Donaire,Rachit Mehra,Romeo Ortega,Sumeet Satpute,Jose Guadalupe Romero,Faruk Kazi,Navdeep Singh +6 more
TL;DR: A new, fully constructive, procedure to shape the energy for a class of mechanical systems that obviates the solution of PDEs is proposed.
