Online Modal Identification of Concrete Dams Using the Subspace Tracking-Based Method
Shock and Vibration, 2019 To investigate the time-varying dynamic characteristics of concrete dams under the excitation of large earthquakes for online structural health monitoring and damage evaluation, an online modal identification procedure based on strong-motion records is ...

Subspace Identification for Industrial Processes
Trends in Computational and Applied Mathematics, 2011 Summary: Subspace identification has been a topic of research along the last years. Methods as MOESP and N4SID are well known and they use the LQ decomposition of certain matrices of input and output data. Based on these we introduce the MON4SID method, which uses the techniques MOESP and N4SID.

Stochastic Subspace Method for Experimental Modal Analysis
MATEC Web of Conferences, 2016 The formula of stochastic subspace identification method is deduced in details and the program is written out. The two methods are verified by a vibration test on a 5-floor rigid frame model.

Recursive Delta-Operator-Based Subspace Identification with Fixed Data Size
Complexity, 2023 This paper proposes a recursive delta-operator-based subspace identification method with fixed data size. The majority of existing subspace identification methods are constrained to discrete-time systems because of the disparity in Hankel matrices ...

Recursive Parsimonious Subspace Identification for Closed-Loop Hammerstein Nonlinear Systems
IEEE Access, 2019 In this paper, a recursive closed-loop subspace identification method for Hammerstein nonlinear systems is proposed. To reduce the number of unknown parameters to be identified, the original hybrid system is decomposed as two parsimonious subsystems ...

Closed-Loop Continuous-Time Subspace Identification with Prior Information
Mathematics, 2023 This paper presents a closed-loop continuous-time subspace identification method using prior information. Based on a rational inner function, a generalized orthonormal basis can be constructed, and the transformed noises have ergodicity features.
