Balanced truncation of linear time-varying systems
Balanced truncation is a well-known model reduction technique for
linear time-invariant systems. In this talk we will see that many of
the attractive properties of balanced truncation can be generalized
and hold for linear time-varying systems. For example, a truncated
input-output stable system is input-output stable, and a priori
worst-case bounds on the approximation error exist. We will illustrate
the method on a model of a diesel exhaust catalyst.
