Stabilization of closed sets for passive systems, part II: Passivity-based control
— In this paper we explore the stabilization of closed invariant sets for passive systems, and present conditions under which a passivity-based feedback makes the set stable, sem...

Stabilization of closed sets for passive systems, part I: Reduction principles
— Given an unforced nonlinear system and two nested closed and invariant sets Γ ⊂ O, we present reduction principles allowing one to extrapolate the properties of stability, a...

Passivity-Based Switching Control for Stabilization of Wheeled Mobile Robots
— We propose a novel switching control law for the posture stabilization of a wheeled mobile robot, that utilizes the (energetic) passivity of the system’s open-loop dynamics w...

Control of underactuated mechanical systems: Observer design and position feedback stabilization
We identify a class of mechanical systems for which a globally exponentially stable reduced order observer can be designed. The class is characterized by (the solvability of) a set...

A scaled bilateral control system for experimental 1-D teleoperated nanomanipulation applications
— In this work, teleoperated nanomanipulation with force feedback is demonstrated by using an atomic force microscope on the slave side and a haptic device on the master side. Th...
