Modelling of electromechanical systems with switch circuits by using transmission elements
The modelling via transmission elements, which was originally introduced to model the kinematics and dynamics of multi-body systems, is applied to modelling electric drive systems with switch circuits in this article. This approach is implemented in C++ in the simulation software DriveControl DC Engine which is designed to model and simulate mechatronic systems in the drive engineering by the department of advanced engineering of the Bosch Rexroth AG. The switch elements, used in the power converters of electric drive systems, are treated as ideal switches and are described in an efficient, stable way. Discontinuities caused by the ideal switch models are dealt with an event-handling algorithm. The application example is a complete permanent-magnet-synchronous-motor (PMSM) drive system. A benchmark simulation is carried out to demonstrate this approach's performance in terms of computational time and accuracy.
