Abstract

The demand to ever increse realism and scope of models routinely exceeds the currently available computing power and thus requires thoughts on improving simulation efficiency. This is especially true for real-time simulations, where ficed timing constraints do not allow to just "wait a bit longer". This paper presents a new approch in Modelica that allows a modeler to separate a model into different partitions for which individual solvers can be assigned. In effect, this allows to use multi-rate and multi-method time integration schemes that can contribute to improve the efficiency ofa (real-time) simulation. The first part of the paper discusses basic consideration relating to modular (real-)time integration. Afterwards, the implemention of a convenient Modelica libarary for the partitioning of physical models is briefly described. Finally, the presented libarary is used to partition a detailed six degree of freedom robot model for modular simulation. the simulation performacne of the partitioned model is compared to the simulation performance achieved by using "conventional" global solvers.[...]
