Matrix normal distribution and elliptic distribution [PDF]

open access: yesarXiv
In this paper, we introduce the matrix normal distribution according to the tensor decomposition of its covariance. Based on the canonical diagonal form, the moment generating function of sample covariance matrix and the distribution of latent roots are explicitly calculated. We also discuss the connections between matrix normal distributions, elliptic

Adaptive virtual admittance control of bidirectional DC/DC converters for DC bus voltage ripple suppression in DC microgrids

open access: yesInternational Journal of Electrical Power & Energy Systems
DC microgrids have the risk of wideband DC bus voltage ripples. The ripple frequency may vary with system operating conditions, increasing the difficulty in voltage ripple suppression.
