Abstract

Lyapunov stability of linear commensurate order fractional systems is investigated in this paper. The connection between the fractional system poles and the decrease of the fractional Lyapunov function is presented as the key point to analyze system stability. LMI conditions depending on the A matrix eigenvalues are derived for a two derivatives fractional differential equation, which is considered as a generic case for more complex systems.
