Description
MODHOC (Multi Objective Direct Hybrid Optimal Control) is a toolbox for the design, optimisation and trade off study of space systems and missions.
It solves general nonlinear multi phase optimal control problems, automatically computing a well spread set of optimal trade off solutions. In addition, it is able to handle discrete optimisation parameters.
In order to do so, MODHOC combines a direct transcription method based on finite elements, a global multi objective optimisation algorithm combining evolutionary heuristics and mathematical programming.
MODHOC has been applied to a variety of applications: from the optimisation of launch vehicles and their ascent, abort and re entry trajectories, to the design of the optimal deployment of constellations of satellites, to the design of multi target missions.
In this paper, the main elements of MODHOC are described and the application of the software in space and non space related sample problems is demonstrated.
