Application for Optimization of Control Parameters for Multi-body and Hydraulics System by using FMU

Abstract

We developed a simulation environment using FMU (Function Mockup Unit) as performance prediction method in the early stage of development. In this environment, hydraulic controller parts are modeled in Dymola which is one of 1D simulation tools based on Modelica language and controlled mechanics parts are modeled in Simpack which is multibody simulation tool. We created a total system model connected to hydraulic controller parts and mechanics parts by using FMI (Function Mockup Interface). Hydraulics and controller parts are converted to FMU by Dymola, and are incorporated in Simpack mechanical model. Furthermore, we applied the system model optimization to control parameters by using Isight.
