Robust Impedance Emulation for Transmission Line Interface in Power-Hardware-in-the-Loop Applications: Optimal Filter Approach

IEEE Open Journal of the Industrial Electronics Society
Power-hardware-in-the-loop (PHIL) simulation infrastructure is an invaluable tool for testing and validating emerging technologies expected to be connected to power grids. As such, PHIL closed-loop stability is a crucial factor to consider when designing

Structured dissociative PCA methods for high dimensional neuroimaging signal decomposition

Scientific Reports
Sparse principal component analysis (SPCA) and independent component analysis (ICA) pipelines are widely used for fMRI blind source separation. However,  applying sparsity and independence constraints in isolation can distort spatial coherence and ...

Interconnection Between Schur Stability and Structured Singular Values

Contemporary Mathematics
In this paper, we present new results on the interconnections between Schur stability and structured singular values of real-valued matrices, denoted as Rn×n . Most new findings are obtained for n = 2 and n = 3. These novel insights into the relationship between Schur stability and structured singular values are developed by applying various tools from

The Active Optics System on the Vera C. Rubin Observatory: Optimal Control of Degeneracy among the Large Number of Degrees of Freedom

The Astrophysical Journal
The Vera C. Rubin Observatory is a unique facility for survey astronomy that will soon be commissioned and begin operations. Crucial to many of its scientific goals is the achievement of sustained high image quality, limited only by the seeing at the ...

Computation and applications of the structured singular value [PDF]

, 1997
This work develops a number of new algorithms for the computation of the convex estimate, ¿tco, of the structured singular value, fj. The basis for these algorithms lies in an application of the geometric form of the Hahn-Banach theorem Dual methods are shown to be more useful than their primal counterparts when determining Ha.
