Automatic modal parameters identification and uncertainty quantification based on block-bootstrap and multi-stage clustering under ambient excitation

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
This study proposes an algorithm for autonomous modal estimation to automatically eliminate false modes and quantify the uncertainty caused by the clustering algorithm and ambient factors. This algorithm belongs to the stochastic subspace identification (

Deterministic-Stochastic Subspace Identification of the Modal Parameters of a Machine Tool During Milling

open access: yesJournal of Manufacturing and Materials Processing
Modal analysis is a standard tool for evaluating the dynamic behaviour of machine tools. Since the dynamic behaviour can differ for operating and analysis conditions, the use of operational modal analysis for machine tools has been researched over the ...

Automated Harmonic Signal Removal Technique Using Stochastic Subspace-Based Image Feature Extraction

open access: yesJournal of Imaging, 2020
This paper presents automated harmonic removal as a desirable solution to effectively identify and discard the harmonic influence over the output signal by neglecting any user-defined parameter at start-up and automatically reconstruct back to become a ...

Model-Free Predictive Anti-Slug Control of a Well-Pipeline-Riser [PDF]

open access: yesModeling, Identification and Control, 2016
Simplified linearized discrete time dynamic state space models are developed for a 3-phase well-pipeline-riser and tested together with a high fidelity dynamic model built in K-Spice and LedaFlow. In addition the Meglio pipeline-riser model is used as an

Trust‐region filter algorithms utilizing Hessian information for gray‐box optimization

open access: yesAIChE Journal, EarlyView.
Abstract Optimizing industrial processes often involves gray‐box models that couple algebraic glass‐box equations with black‐box components lacking analytic derivatives. Such systems challenge derivative‐based solvers. The classical trust‐region filter (TRF) algorithm provides a robust framework but requires extensive parameter tuning and numerous ...

Subspace Identification Method for Combined Deterministic-Stochastic Bilinear Systems [PDF]

open access: yesIFAC Proceedings Volumes, 2000
Abstract In this paper, a 'four-block' subspace system identification method for combined deterministic-stochastic bilinear systems is developed. Estimation of state sequences, followed by estimation of system matrices, is the central component of subspace identification methods.

Extracting inter-area oscillation modes using local measurements and data-driven stochastic subspace technique

open access: yesJournal of Modern Power Systems and Clean Energy, 2017
In this paper, a data-driven stochastic subspace identification (SSI-DATA) technique is proposed as an advanced stochastic system identification (SSI) to extract the inter-area oscillation modes of a power system from wide-area measurements. For accurate

Subspace System Identification of the Kalman Filter [PDF]

open access: yesModeling, Identification and Control, 2003
Some proofs concerning a subspace identification algorithm are presented. It is proved that the Kalman filter gain and the noise innovations process can be identified directly from known input and output data without explicitly solving the Riccati ...

Correlation signal subset-based stochastic subspace identification for an online identification of railway vehicle suspension systems

open access: yesVehicle System Dynamics, 2020
Monitoring the condition of suspension systems is significant to ensure the safe operation of modern railway vehicles. For this purpose, an online modal identification scheme, denoted as Correlation Subset based Stochastic Subspace Identification (CoS ...
