METHOD OF DETERMINING THE FREQUENCY CHARACTERISTICS OF THE SYSTEMS OF AUTOMATIC CONTROL (SPOSOB OPREDELENIYA CHASTOTNYKH KHARAKTERISTIK SISTEM AVTOMATICHESKOGO UPRAVLENIYA),

Abstract

A method is provided for determining the frequency characteristics of systems of automatic control by means of measuring Fourier's coefficient of the stationary response (reaction) of such a system under the sinusoidal action on it. It has the distinguishing feature that for the purpose of measuring Fourier's coefficients without making use of the operation of multiplication, the determined response of the system is passed onto the oscillatory link with two integrators and one inverter, the link thus modeling the conservative linear harmonic oscillator with natural frequency, equal to the frequency of the outer action. Then the integrators of the model of the oscillatory are cut in for the time equal to one period of the sinusoidal outer action at the moment of its transition through the zero value, with a positive derivative while the values of the cophasal and quadrature components of the response of the system is fixed on the output of the integrators of the model after their being cut off.
