Model Based Control System Design Using SysML, Simulink, and Computer Algebra System

Abstract EN

The Systems Modeling Language (SysML) is a standard, general-purpose, modeling language for model-based systems engineering (MBSE).

SysML supports the specification, analysis, and design of a broad range of complex systems such as control systems.

The authors demonstrate how they can integrate a SysML modeling tool (IBM Rational Rhapsody) with a proprietary simulation tool (MathWorks Simulink) and a Computer Algebra System (CAS) to validate system specification.

The integration with Simulink enables users to perform systems engineering process in a SysML model, while designing continuous control algorithms and plant behavior in Simulink, and to validate the behavior by simulating the overall composition in Simulink.

The integration with a CAS enables the evaluation of mathematical constraints defined in SysML parametric diagrams.

The authors also show the overall approach using a Dual Clutch Transmission (DCT) and a Cruise Control System as examples.
