Abstract

This paper introduces a periodic disturbance compensator that uses feedforward control to reduce noise indirectly in the system. This technology reduces the influence of periodic disturbances in a multi-input system by applying a different physical quantity input to a different source from that of the disturbance source. The control object is modeled to compensate for the periodic disturbances caused by the noise source by applying a different physical quantity. The control signal is generated from the aforementioned model and measurement results of the influence of the disturbance, and it is input to the different source on a feedforward basis. We applied our proposed periodic disturbance compensator for the electrophotographic process (EP), thereby determining that the periodic disturbance (image noise) caused by eccentric rotation is effectively reduced by modulating the laser power without correction for the noise source.
