This article is dedicated to model order reduction of linear time-invariant passive systems, ie,
positive real (PR) systems, based on the balanced truncation (BT) concept. The main feature …

In this paper, we discuss the problem of model order reduction for positive real systems
based on balancing methods. The mixed gramian balanced truncation (MGBT) method …

Reducing the order of positive real and bounded real systems has received great interest
over the years. Several methods have been published regarding these issues which are …

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. The …

Based on the approximate finite-time Gramians, this paper studies model order reduction
method of port-Hamiltonian systems with inhomogeneous initial conditions. The …

This paper proposes a novel algorithm, termed Mixed Riccati–Lyapunov Balanced
Truncation (MRLBT), tailored for order reduction of Linear Time-Invariant Continuous-Time …

In this paper, we present an adaptive framework for constructing a pseudo‐optimal reduced
model for the frequency‐limited‐optimal model order reduction problem. We show that the …

The existing frequency-limited interval-based model reduction techniques can generate
unstable models for a stable continuous-time linear system. Further, some current methods …

In time-limited model order reduction, a reduced-order approximation of the original high-
order model is obtained that accurately approximates the original model within the desired …

This thesis investigates the H 2-optimal model order reduction problem within finite time and
frequency intervals. Several oblique projection-based algorithms are proposed that …
