Identification Control Objects in Normal Operation

Abstract

The article discusses a device that performs the identification of the existing control facilities in the normal operation without the use of additional (test) signals at their input. At the same time the problem of determining the instantaneous values of multipoint two-parameter characteristics significantly unsteady multi-input linear object with the same speed as produced calculations solved. Possibility of technical implementation of the continuous removal of two-parameter frequency response for multi-input significantly unsteady automation object without affecting its mode of operation is presented in the article. The principle of operation of the device based on the allocation of the input and output signals of the linear object of the harmonic components of the fundamental frequency and determination of the attenuation and phase shift (i.e., distortion in amplitude and phase) of each harmonic in the process of passing through the control object.
