Closed Loop Subspace Identification [PDF]
Modeling, Identification and Control, 2005 A new three step closed loop subspace identifications algorithm based on an already existing algorithm and the Kalman filter properties is presented. The Kalman filter contains noise free states which implies that the states and innovation are uneorre ...

Data-Driven Predictive Control With Switched Subspace Matrices for an SCR System
IEEE Access, 2022 Selective catalytic reduction (SCR) systems are distributed systems with strong time-varying parameter characteristics such that an accurate model for it is difficult to establish.

Subspace Identification of Large-Scale Interconnected Systems [PDF]
IEEE Transactions on Automatic Control, 2014 We propose a decentralized subspace algorithm for identification of large-scale, interconnected systems that are described by sparse (multi) banded state-space matrices. First, we prove that the state of a local subsystem can be approximated by a linear combination of inputs and outputs of the local subsystems that are in its neighborhood. Furthermore,

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.

Closed and Open Loop Subspace System Identification of the Kalman Filter [PDF]
Modeling, Identification and Control, 2009 Some methods for consistent closed loop subspace system identification presented in the literature are analyzed and compared to a recently published subspace algorithm for both open as well as for closed loop data, the DSR_e algorithm.

Efficient Forced Response Computations of Acoustical Systems with a State-Space Approach
Acoustics, 2021 State-space models have been successfully employed for model order reduction and control purposes in acoustics in the past. However, due to the cubic complexity of the singular value decomposition, which makes up the core of many subspace system ...

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 ...
