Abstract :
The problem of harmonic disturbances rejection in digital control systems is discussed. The design method based on the formation of two-time-scale motions in the closed loop system is used. The pulse transfer function properties are investigated. The relationship for the sampling period calculation in accordance with the requirement to harmonic disturbances rejection is obtained. Finally, an example with simulation results is presented
