Parametric identification of the control objects functioning in closed systems.

The task of identification of control objects and the perturbation shaping filter in the closedsystems of regulation functioning in a mode of normal maintenance in the presence of perturbinginfluences is considered. The composition of system of regulation includes the linear object whichoutput variable is stabilized concerning constant value by means of feedback.As criterion of identification the condition of equality of mutually correlative function of anobservable output signal and perturbing influence and correlative function of an observable outputsignal and a reset estimation of perturbing influence is accepted. Identifiability conditions inclosed system at which on observations of output variable system the task of parametric identificationof transmitting function of object and the perturbation shaping filter can be solved are defined.The developed algorithm of identification allows on the basis of the current information onan output variable to define parameters of the shaping filter of perturbation and transmitting functionof object. Result of practical implementation of algorithm is obtaining of unbiased and consistentestimations of required parameters of transmitting functions which can find application atsynthesis of closed systems of regulation and adjustment of regulators in the course of normalmaintenance.
