Vp. Zhukov, Method of radial drift for qualitative study of the properties of the nonlinear dynamic systems. II. Study of asymptotic system stability, AUT REMOT R, 62(2), 2001, pp. 190-206
The method of monotonic radial drift proposed in the first part of this pap
er was used to study the conditions for asymptotic stability (in large) of
the equilibrium states of dynamic nonautonomous nonlinear systems of an arb
itrary order. It enabled the author to obtain new conditions for asymptotic
stability of these states which allow one to carry out studies mostly on t
he basis of direct information about the right-hand side of the system. The
method enables one to study systems to which neither the first nor second
Lyapunov method is applicable.
