System Identification Based on Invariant Subspace

IEEE Transactions on Automatic Control, 2022
This article proposes a novel system identification method based on the notion of invariant subspace. It is shown that when the system input and output asymptotically converge onto an invariant subspace, a new form of regression can be obtained.

Cross-domain intelligent fault classification of bearings based on tensor-aligned invariant subspace learning and two-dimensional convolutional neural networks

Knowledge-Based Systems, 2020
Rolling element bearings faults are one of the main causes of breakdown of rotating machines. Aside from this, due to variation of operating condition, domain shift phenomenon results in important detection performance deterioration.

Idea of invariant subspace combined with elementary integral method for investigating exact solutions of time-fractional NPDEs

Applied Mathematics and Computation, 2018
In this paper, inspired by the idea of invariant subspace method and combined with elementary integral method, we introduced a novel approach for investigating exact solutions of a time-fractional nonlinear partial differential equation (NPDE).

An Invariant Subspace Theorem and Invariant Subspaces of Analytic Reproducing Kernel Hilbert Spaces - II

, 2013
This paper is a follow-up contribution to our work (Sarkar in J Oper Theory, 73:433–441, 2015) where we discussed some invariant subspace results for contractions on Hilbert spaces. Here we extend the results of (Sarkar in J Oper Theory, 73:433–441, 2015)
