Virtual Inertia Control and Small-Signal Stability Analysis of Electric Vehicle [PDF]

International Journal of Industrial Electronics, Control and Optimization, 2023
In electric vehicles (EVs), the small size of the dc link capacitor results in significant voltage deviations when there are changes in load or uncertain fluctuations from the power resources. This causes a decline in voltage quality.

Sensitivity and stability: A signal propagation sweet spot in a sheet of recurrent centre crossing neurons

, 2008
In this paper we demonstrate that signal propagation across a laminar sheet of recurrent neurons is maximised when two conditions are met. First, neurons must be in the so-called centre crossing configuration.
