Benchmark Model Templates
This page specifies templates for the types of models used as benchmark systems. In particular, the naming schemes established here are used in the corresponding data sets for all benchmarks. For example, always serves as the name of the component matrix applied to the state
in a linear time-invariant system.
For all models we assume an input
, with components
,
a state
,
and an output
.
For all parametric models, we assume each component has
parameters; in cases where a component has fewer than
parameters, the extras are treated as
.
Some benchmarks (e.g., Bone Model) have a constant forcing term, in which case, it is assumed that
is identically
