There has been considered the solution of a problem of compensation of unknown periodic disturbances for linear plants with control delay. It was assumed that disturbance was equal to the finite sum of sinusoidal signals with unknown amplitudes, phases, and multiple frequencies. An adaptive frequency identifier of sinusoidal signals based on speed gradient method has been used to develop a compensator. There has been used an auxiliary circuit for disturbances compensation. The resulting algorithm was consolidated to control dynamic networks with a communication delay. As a result the synthesized control system provides accurate compensation of disturbances. Simulation results illustrating effectiveness of the proposed scheme are provided.
