Abstract

A controllable self-oscillating system with self-switching that includes additional feedback in an oscillator consisting of a nonlinear amplifier, first-order and second-order filters, and a delay line configured into a closed loop is proposed. A mathematical model of the system and results of its numerical analysis are presented. It is shown that, in a system with time lag and a large inertia parameter, oscillation may become chaotic even if only regular oscillation takes place in the absence of self-switching. The effect of additional feedback on an oscillator-containing system without an inertia element, second-order filter, or delay line is considered.
