Suppression of Self-Modulation in the Self-Oscillator with Delayed Feedback Using the Method for Chaos Control

摘要

A method to suppress self-modulationory in the self-oscillatory systems with delayed feedback (DF) is proposed. The method is based on an additional DF circuit whose parameters are chosen in such a way that the signal components at the fundamental and spurious frequencies having passed through the two branches of the DF circuit have equal and opposite phases, respectively, so that the spurious components are suppressed. The results of the numerical simulations show that the method allows a two- to threefold increase in the range of parameters that corresponds to the stability of the stationary single-frequency generation and an increase in the generation power by about 30%.
