A novel Hankel norm approximation-based AGC for a hydro-dominated power system [PDF]
Scientific ReportsAnalyzing power system disturbances for automatic generation control (AGC) requires solving a large set of differential equations, which remains computationally demanding even in linearized form and hence limits the practical implementation of most ...

Hankel-norm approximation of FIR filters: a descriptor-systems based approach [PDF]
International Journal of Control, 2010 We propose a new method for approximating a matrix finite impulse response (FIR) filter by an infinite impulse response (IIR) filter of lower McMillan degree. This is based on a technique for approximating discrete-time descriptor systems and requires only standard linear algebraic routines, while avoiding altogether the solution of two matrix Lyapunov

Hankel-norm approximation of large-scale descriptor systems [PDF]
Advances in Computational Mathematics, 2020 AbstractHankel-norm approximation is a model reduction method for linear time-invariant systems, which provides the best approximation in the Hankel semi-norm. In this paper, the computation of the optimal Hankel-norm approximation is generalized to the case of linear time-invariant continuous-time descriptor systems.

Numerical approach for the frequency-weighted Hankel-norm approximation [PDF]
2001 European Control Conference (ECC), 2001 We derive new projection formulas for the model reduction method based on the frequency-weighted Hankel norm approximation (FWHNA). These formulas extend the applicability of the FWHNA method to frequency weights expressed as antistable right/left invertible rational matrices.
