Sparse plus low-rank identification for dynamical latent-variable graphical AR models
Junyao You, Chengpu Yu
This paper focuses on the identification of graphical autoregressive models with dynamical latent variables. The dynamical structure of latent variables is described by a matrix po…

Subspace Identification of Large-Scale 1D Homogeneous Networks
Chengpu Yu, Michel Verhaegen, Anders Hansson
This paper considers the identification of large-scale 1D networks consisting of identical LTI dynamical systems. A new subspace identification method is developed that only uses l…

Gray Box Identification of State-Space Models Using Difference of Convex Programming
Chengpu Yu, Lennart Ljung, Michel Verhaegen
Gray-box identification is prevalent in modeling physical and networked systems. However, due to the non-convex nature of the gray-box identification problem, good initial paramete…
