Euler angles is a popular representation in many applications, but yield models having singular dynamics. This issue is addressed via non-singular representations, operating in dimensions higher than 3. Unit quaternions and the Direction Cosine Matrix are the best known non-singular representations, and favoured in challenging aeronautic and aerospace applications. All nonsingular representations yield invariants in the model dynamics, i.e. a set of nonlinear algebraic conditions that must be fulfilled by the model initial conditions, and that remain fulfilled over time. However, due to numerical integration errors, these conditions tend to become violated when using standard integrators, making the model inconsistent with the physical reality. This issue poses some challenges when non-singular representations are deployed in optimal control. In this paper, we propose a simple technique to address the issue for classical integration schemes, establish formally its properties, and illustrate it on the optimal control of a satellite. date: 2015 date_type: published publisher: IEEE pagerange: 620-625 event_title: 54th Conference on Decision and Control event_location: Osaka, Japan event_dates: December 15-18, 2015 event_type: conference id_number: doi:10.1109/CDC.2015.7402298 refereed: TRUE isbn: 978-1-4799-7886-1 book_title: 54th IEEE Conference on Decision and Control (CDC) official_url: http://doi.org/10.1109/CDC.2015.7402298 citation: Gros, Sebastien and Zanon, Mario and Diehl, Moritz Baumgarte stabilisation over the SO(3) rotation group for control.
