DyOS

 

A large class of dynamic optimization problems involve models given by differential-algebraic equations.

DyOS allows the model to be accessed via a so-called Equation Set Object (ESO) interface, a standard developed in the Cape-Open project. Models can be imported in DyOS as Functional Mock-up Units (FMU). But also the free model server ACSAMMM can be used (using Modelica as model language).

DyOS features state-of-the-art numerical solution methods, among them an automatic adaptation of the control profile discretization. DyOS has successfully been used to solve multi-stage problems, mixed integer dynamics optimization problems, dynamic parameter and input estimations, and optimal experimental design problems.

DyOS has been developed at AVT.PT and is still under continuous development at AVT.SVT. We are grateful for funding from DFG, EU, BMBF, BMWi, Helmholtz and various private entities that have contributed directly or indirectly to DyOS.
