Optimal Hankel norm model reduction by truncation of trajectories

We show how optimal Hankel-norm approximations of dynamical systems allow for a straightforward interpretation in terms of system trajectories. It is shown that for discrete time single-input systems optimal reductions are obtained by cutting ’balanced trajectories’, i.e., by disconnecting the past and future in the input-output pairs relating to leftand right singular vectors of the system. A ...

OPTIMAL HANKEL−NORM APPROXIMATION OF IIR BY FIR SYSTEMS (TueAmPO4)

This paper presents a constructive method to (sub)optimal finite impulse response (FIR) approximation of a given infinite impulse response (IIR) model. The method minimizes the Hankel norm of approximation error by using the explicit solution of norm−preserve dilation problem. It has the advantage over the existing methods that it provides an explicitly constructive solution and allows the trad...

Reduction of Large Scale Systems Using Hankel Norm Approximation

In this paper a popular time domain reduction method based on hankel norm approximation (HNA) is explored. This method suffers from a drawback of not matching steady state values for some of the systems. A very simple method is given to remove this drawback and an improvement is made so that the steady state value of the original model is also preserved in the reduced model. This increases sign...

Frequency-weighted optimal Hankel-norm approximation of stable transfer functions

The present paper presents a method of frequency shaping the error obtained by performing an optimal Hankel-norm approximation of a scalar, finite-dimensional, linear, time-invariant system. The optimal Hankel-norm approximation procedure finds a transfer function (or transfer function matrix) of prescribed order which approximates a given transfer function (or transfer function matrix) of grea...

Power System Model Reduction with Grid-Connected Photovoltaic Systems Based on Hankel Norm Approximation

In order to ensure stability of the system, transmission and distribution studies need to be performed. These simulation studies can be time consuming due to high complexity of the system. This paper investigates model reduction on a power system with photovoltaic generation. This is done by decreasing the complexity of the detailed model, which leads to a smaller simulation time, but still mai...
