Data-driven model order reduction of linear switched systems in the Loewner framework

IV Gosea, M Petreczky, AC Antoulas - SIAM Journal on Scientific Computing, 2018 - SIAM
The Loewner framework for model reduction is extended to the class of linear switched
systems. One advantage of this framework is that it introduces a trade-off between accuracy …

Balanced truncation for linear switched systems

IV Gosea, M Petreczky, AC Antoulas, C Fiter - Advances in Computational …, 2018 - Springer
We propose a model order reduction approach for balanced truncation of linear switched
systems. Such systems switch among a finite number of linear subsystems or modes. We …

Reachability and observability reduction for linear switched systems with constrained switching

M Baştuğ, M Petreczky, R Wisniewski, J Leth - Automatica, 2016 - Elsevier
We present an algorithm for reducing the number of continuous states of a discrete time
linear switched system, such that the reduced system has the same input–output behavior …

Model reduction by moment matching for linear switched systems

M Bastug, M Petreczky, R Wisniewski, J Leth - arxiv preprint arxiv …, 2014 - arxiv.org
Two moment-matching methods for model reduction of linear switched systems (LSSs) are
presented. The methods are similar to the Krylov subspace methods used for moment …

[PDF][PDF] Model order reduction of linear and nonlinear systems in the Loewner framework

IV Gosea - Jacobs University Bremen, 2017 - d-nb.info
The Loewner framework is an interpolatory model order reduction technique that uses
measured or computed data, eg, measurements of the frequency response of a to-be …

Model reduction by nice selections for linear switched systems

M Baştuğ, M Petreczky, R Wisniewski… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
A moment-matching method for model reduction of linear switched systems (LSSs) is
presented. The method can be seen as a non-trivial extension of the Krylov subspace …

Model reduction of linear switched systems by restricting discrete dynamics
