Abstract

In this paper is presented the improvement of the stability of a relay control system whose nonlinear part contains an on-off element with generalized characteristic which may generates all types of single polarity characteristics including those with and without hysteresis. It is shown that for some of these characteristics no self-oscillations exist and therefore the relay control system is stable.
