GESOP^® Facts

Optimal control and parameter optimization tools embedded into a graphical user interface

• Four optimization programs PROMIS, SOCS, TROPIC and CAMTOS all using state- or/and control parametrization.
• State of the art optimization methods: multiphase multiple shooting and colloction using NLP-slover SNOPT and high performancs optimizer SOCS (Licensed by The Boeing Company).
• Simulation program with can be used in three different modes.
• Initial guess generator which either integrates the dynamic systems with user specified control laws or control time histories.
• Programming interface which gives the user a clear structure, how to program his own optimization problem in Fortran 77, C, Ada 95 or Matlab scripts (The MathWorks).
• Simulink interface which allows the user to link and optimize his models created by Simulink (The MathWorks).
• Graphical user interface which allows operation of the software intuitively and help significantly in reducing problem solving time.
• Tools Inspector which supports initializing the problem and lets the user set various parameters for simulation and optimization.
• Graphical input facility which enables a user to graphically define, modify, or refine the various discretization grids, set the real parameters, activate or deactivate the constraints. Phase times with their upper and lower bounds can be set. It also supports specifying initial estimates for the optimization parameters as well as modifying intermediate results.
• Graphical output display which allows a quick overview over the various state/control/auxiliary function time histories.
• Result summary which sum up all constraint violations, parameter values and function time histories in text format.
• Optimization monitor GISMO which graphically displays the cost function, the convergence criteria and selected constraints as well as control- and state time histories as functions of the optimization iterations online during the optimization process. The graphical display setup may be easily customized by the user.
• Export filter which allows the user to post-process all simulation data in the MATLAB environment. To this end the GESOP generated simulation data are exported in a form that MATLAB can easily read and process. Spreadsheets, like Microsoft Excel, can import this data format, too.
