    08: Optimization and Dynamics
    Oral presentation at the conference
    Layout design of spacecraft module belongs to scheme design problem, which has been proved to be NP hard. This problem has not only computing complexity but also engineering complexity, and it is more difficult to tackle the challenge of practical application in engineering. In practical engineering, the dimension of satellite configuration is usually unknown and needs to be optimized...

  2. 54. WORHP Multi-Core Interface, Parallelisation Approaches for an NLP Solver
    Mr Sören Geffken (Universität Bremen)
    16/03/2016, 08:20
    08: Optimization and Dynamics
    Oral presentation at the conference
    The goal of this talk is to present current research activities aiming at improved efficiency and stability within the ESA NLP-Solver WORHP. It is designed to solve high dimensional sparse non-linear optimisation problems. The underlying SQP method is inherently sequential, therefore parallelism cannot be exploited straightforwardly. In order to obtain the best solver performance the...

  3. 50. Non-Keplerian Trajectory Planning via Heuristic-Guided Objective Reachability Analysis
    David Surovik (University of Colorado at Boulder)

    08: Optimization and Dynamics
    Oral presentation at the conference
    In many space exploration scenarios of great interest, such as close-range study of asteroids and comets, spacecraft motion cannot be effectively approximated using Kepler's laws. Furthermore, special dynamical structures such as periodic orbits are not inherently associated with specific science requirements and serve only as a limited framework for facilitating operations. To broaden the...

  4. 34. Analytical Approximation for the Multiple Revolution Lambert's Problem
    Dr Claudio Bombardelli (Space Dynamics Group, Technical University of Madrid)
    16/03/2016, 09:00
    08: Optimization and Dynamics
    Oral presentation at the conference
    An approximate analytical solution of the multiple revolution Lambert's problem is presented. The solution is obtained based on a variation of parameters approach and offers remarkable accuracy near the minimum energy condition. Consequently, the method is useful for rapidly obtaining low delta-V solutions for interplanetary trajectory optimization. In addition, the method can be employed to...

  5. 138. Understanding concepts of Optimization and Optimal Control with WORHP Lab
    Dr Matthias Knauer (Universität Bremen)
    16/03/2016, 09:40
    08: Optimization and Dynamics
    Oral presentation at the conference
    The ESA-NLP solver WORHP is already used in several academic and industrial projects in a wide range of applications, as aerospace, automotive or logistics. Currently over 500 users worldwide code their problem formulations using the the standard interfaces to Fortran, C/C++ and MATLAB. To simplify the formulation of optimisation problems for demonstration and educational purposes...
