Characterizing the codimension of zero singularities for time-delay systems: a link with Vandermonde and Birkhoff incidence matrices

I Boussaada, SI Niculescu - Acta Applicandae Mathematicae, 2016 - Springer
The analysis of time-delay systems mainly relies on detecting and understanding the
spectral values bifurcations when crossing the imaginary axis. This paper deals with the …

Balancing with vibration: a prelude for “drift and act” balance control
