Control of mechanical systems on Lie groups based on vertically transverse functions
(2008-06)"The transverse function approach to control provides a unified setting to deal with practical stabilization and tracking of arbitrary trajectories for controllable driftless systems. Controllers derived from that approach ... -
On the transversality of functions at the core of the transverse function approach to control
(2011-12)"The transverse function approach to control, introduced by Morin and Samson in the early 2000s, is based on functions that are transverse to a set of vector fields in a sense formally similar to, although strictly speaking ... -
New results on robust exponential stability of integral delay systems
(2016-06)"The robust exponential stability of integral delay systems with exponential kernels is investigated. Sufficient delay-dependent robust conditions expressed in terms of linear matrix inequalities and matrix norms are derived ... -
Stability conditions for integral delay systems
(2010)"In this paper we consider a special class of integral delay systems arising in several stability problems of time‐delay systems. For these integral systems we derive stability and robust stability conditions in terms of ... -
Braid solutions to the action of the Gin enzyme
