On frequency- and time-limited H2-optimal model order reduction
Umair Zulfiqar, Victor Sreeram, Xin Du
In this paper, the problems of frequency-limited and time-limited H2-optimal model order reduction of linear time-invariant systems are considered within the oblique projection fra…
Frequency-weighted H2-optimal model order reduction via oblique projection
Umair Zulfiqar, Victor Sreeram, Mian Ilyas Ahmad +1
In projection-based model order reduction, a reduced-order approximation of the original full-order system is obtained by projecting it onto a reduced subspace that contains its do…
Multi-task Learning Based Spoofing-Robust Automatic Speaker Verification System
Yuanjun Zhao, Roberto Togneri, Victor Sreeram
Spoofing attacks posed by generating artificial speech can severely degrade the performance of a speaker verification system. Recently, many anti-spoofing countermeasures have been…
Time- and frequency-limited H2-optimal model order reduction of bilinear control systems
Umair Zulfiqar, Victor Sreeram, Mian Ilyas Ahmad +1
In the time- and frequency-limited model order reduction, a reduced-order approximation of the original high-order model is sought to ensure superior accuracy in some desired time…
Frequency-Limited Pseudo-Optimal Rational Krylov Algorithm for Power System Reduction
Umair Zulfiqar, Victor Sreeram, Xin Du
In this paper, a computationally efficient frequency-limited model reduction algorithm is presented for large-scale interconnected power systems. The algorithm generates a reduced…
Time-limited pseudo-optimal H-model order reduction
Umair Zulfiqar, Victor Sreeram, Xin Du
A model order reduction algorithm is presented that generates a reduced-order model of the original high-order model, which ensures high-fidelity within the desired time interval.…
