For the investigation of the absolute stability of control systems with nonlinearities of the
“backlash” and “stop” type on the basis of VM Popov's criterion, the representation of these …

In this paper there are presented methods of study for the automatic regulation of the
absolute stability in case of the nonlinear dynamical systems. There are specified two …

Many authors, mainly in the Soviet, have discussed the absolute stability of the automatic
control system with one nonlinear element. In practical problems, however, we sometimes …

The stability of the solutions of a certain class of non-linear systems is considered in the first
approximation. The method of Lyapunov functions is used to obtain the sufficient conditions …

The system stability (1.1) is investigated by means of the second method of Liapunoff. At the
same time the necessary and sufficient conditions of absolute stability and absolute …

It is shown how on the basis of the VM Popov frequency criterion [1, 2] one can study, by
means of logarithmic frequency characteristics, the absolute stability of equilibrium state of …

Abstract top This paper discusses asymptotic stability for nonautonomous systems by means
of the direct method of Liapunov. The existence of a positive time-invariant Liapunov …

There obtained, for single-nonlinearity systems, a new frequency condition of absolute
stability improving, for a number of cases, the VM Popov condition and covering, for a class …

Sufficient conditions of interval absolute stability of nonlinear control systems described in
terms of systems of the ordinary differential equations with delay argument and also neutral …
