VESTA is a 3U nanosatellite technology demonstration mission that will test a new two-way VHF Data Exchange System (VDES) payload developed by Honeywell for the exactEarth advanced maritime satellite constellation.The 4kg satellite has three-axis pointing capability, an SEU tolerant on-board computer, VxWorks operating system and also flies a Commercial-Off-The-Shelf (COTS) VHF deployable antenna system developed by Innovative Solutions in Space for the VDES transceiver.
It is well known that one of the most used tools in the stability analysis of VDEs is the Lyapunov approach [22-28].
For such a reason, in this paper we focus on the following homogeneous VDE:
For the sake of completeness, there is also another type of VDE widely used in literature (see, e.g., [5, 6])
Here we would like to add another piece to the framework regarding the analysis of VDE behaviour, by considering hypotheses based on the sign of the coefficients and of their first and second differences.
The task of qualitative reverse engineering for our crane case is then defined as, Given examples of time behaviors of Vdes, F, X, V, Fi, and DFi, find a qualitative relation between the control force F and the other quantities.
This tree gives the qualitative constraints on the function that maps the variables X, V, Fi, DFi, and the relative carriage velocity Vrel (relative to the desired velocity Vdes, Vrel = V-Vdes) into the control force F.
