Robust exponential stability of nonlinear impulsive switched systems with time-varying delays [PDF]

open access: yes, 2012
This paper deals with a class of uncertain nonlinear impulsive switched systems with time-varying delays. A novel type of piecewise Lyapunov functionals is constructed to derive the exponential stability.

Nonlinear Error Correction Models [PDF]

open access: yes, 2002
The relationship between cointegration and error correction (EC) models is well characterized in a linear context, but the extension to the nonlinear context is still a challenge.
