A framework for reduced order modeling with mixed moment matching and peak error objectives

K R Santarelli
2010 Proceedings of the 2010 American Control Conference  
We examine a new method of producing reduced order models for LTI systems which attempts to minimize a bound on the peak error between the original and reduced order models subject to a bound on the peak  ...  We then prove that, for a certain class of LTI systems, the method we propose can be used to produce reduced order models of arbitrary accuracy even when the original system is infinite dimensional.  ...  A MIMO LTI system with impulse response matrix H(t) has L 1 norm given by ||H|| 1 = max i j ∞ 0 |h ij (t)|dt (49) where h ij (t) represents the (i, j)−th entry of H(t).  ...
