Abstract

In rotating servo systems, disturbances which cause rotor vibrations are often periodic. Repetitive control is useful in reducing such periodic rotating vibrations. However, the typical repetitive control has a peculiar weak point. The author tried to solve this problem by means of a new iterative learning compensator. To realise this proposed compensator, several methods including the use of Butterworth band-pass filters, infinite impulse response digital filters, and the fast Fourier transform technique were investigated. A numerical example was used, and numerical simulations were also carried out to confirm the effectiveness of the proposed method. The results proved that it is practical and useful to apply this repetitive control without deteriorating the controlled output of the rotating servo system at any frequency.
