English abstract:
Abstract: This paper compares several regularisation methods for di↵erential-algebraic equation
systems of high di↵erential index by applying them to two model problems. Both problems
are mechanical systems which are described by equation systems of index three, a pendulum
and a double pendulum, where the latter furthermore shows chaotic behaviour. Some methods
turn out to be not suitable at all for high index di↵erential-algebraic equation systems while
the quality of many regularisation methods depends on an adequate choice of parameters,
implementation and the system itself to be solved with the respective method.
