Abstract:
Consideration was given to the conditions for reduction of stability study by the second Lyapunov method of the original nonlinear autonomous dynamic system obeying a system of arbitrary-order ordinary differential equations to stability study of a simpler (abridged) dynamic system using the same method. For a wide class of original nonlinear dynamic systems, sufficient reduction conditions for asymptotic stability and instability were presented.
