Abstract

Multi-disciplinary interactions between flight and structural dynamics, aerodynamics, onboard system dynamics, etc. play an increasingly important role in (modelling of) over-all aircraft flight dynamics. The Modelica modelling language has been especially developed for modelling of such multi-physics systems and is therefore more and more used in the field of aircraft modelling, simulation, and control design. The Functional Mock-up Interface (FMI) offers the possibility to generate software code with standardized interfaces, allowing multi-physical Modelica models to be run in other simulation environments. For control algorithm implementation on (prototype) target hardware or for model implementation on real-time hardware (e.g. for Hardware-in-the-loop testing), automatic code generation from a block diagram specification has become standard practice. In this respect, the Matlab / Simulink environment offers software auto coding for a wide spectrum of target platforms. This paper integrates the code generation capabilities from Modelica (via FMI standard) with those from Matlab/Simulink (Simulink Coder standard), allowing for automatic implementation of multi-physical models and algorithms developed in the Modelica language on the wide range of target platforms supported by the Simulink Coder. The paper describes the development of the underlying toolchain, an example application for a small unmanned test aircraft, as well as some lessons learned.
