METHOD FOR ESTIMATING AMPLITUDE- AND PHASEFREQUENCY RESPONSE CHARACTERISTICS OF CONTROL SYSTEMS

摘要

FIELD: instrumentation engineering. SUBSTANCE: method involves setting inherent stored energy at control system due to giving it respective initial conditions, this energy being used to compensate for transient component in output signal when system is excited by harmonic signal which makes it possible to immediately view forced harmonic oscillation at system output, its amplitude and phase being target parameters. EFFECT: enhanced speed of estimating controlsystem frequency response characteristics.
