Analysis of transient oscillations in systems with MRFT

Abstract

Transient oscillations in relay feedback systems and other nonlinear systems are considered in this chapter. The consideration is based on the dynamic harmonic balance principle presented in the chapter. In addition to the relationship between the amplitude and the frequency of the oscillations, the dynamic harmonic balance involves the relationship between the rates of change of the amplitude and of the frequency, which provides a simple model of oscillations in their transient conditions. The provided theory is illustrated by example of analysis of transient oscillations.
