The compensation of a harmonic perturbation under conditions of a delay in control

The paper is devoted to the development of the methods of compensation of harmonic perturbations based on measurements of the plant output variable. An approach of compensation of a harmonic perturbation of unknown frequency, acting on a linear controlled plant is proposed. Unlike known analogs, in this paper, the problem of perturbation compensation is considered for the case, when the control channel is characterized by a delay.
