Uncertainty quantification in data-driven stochastic subspace identification [PDF]
Mechanical Systems and Signal Processing, 2021 Abstract A crucial aspect in system identification is the assessment of the accuracy of the identified system matrices. Stochastic Subspace Identification (SSI) is a widely used approach for the identification of linear systems from output-only data because it combines a high computational robustness and efficiency with a high estimation accuracy ...

Stochastic subspace identification of modal parameters during ice–structure interaction [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 Identifying the modal parameters of structures located in ice-infested waters may be challenging due to the interaction between the ice and structure. In this study, both simulated data from a state-of-the-art ice–structure interaction model and measured data of ice–structure interaction were both used in conjunction with a covariance-driven stochastic

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.

Deterministic - Stochastic Subspace Identification for Bridges [PDF]
2007 IEEE/SP 14th Workshop on Statistical Signal Processing, 2007 System identification for structural engineering has received significant attention in the last thirty years. With the ever increasing capacity of computing technology, system identification has been applied to important structures such as bridges and aircraft. In the case of bridges, the output can easily be measured by accelerometers.
