We present a complete derivation of coprime factorizations for a class of
multi-dimensional systems containing linear parameter-varying and uncertain
systems. A generalization of coprime factors model reduction using a balanced
truncation approach is then given, with error bounds
on the factorized mapping in the l2-induced norm. The proposed reduction
method is thus applicable to linear parameter-varying and uncertain systems
that do not satisfy the usual l2-induced stability constraint
required by the standard non-factored truncation methods.
