We consider an image motion velocity stabilization system embedded into a space telescope for a scanning optoelectronic observation of terrestrial targets. We have developed model of this system taking into account physical hysteresis of piezo-ceramic driver and a time delay at a forming of digital control. We have presented elaborated algorithms for discrete filtering, digital control and obtained results on analysis of the image motion velocity oscillations in the telescope focal plane.
