Abstract

We consider an image motion stabilization system embedded into a space telescope for a scanning optoelectronic observation of terrestrial targets. Developed model of this system is presented 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 and digital control, obtained results on nonlinear analysis of the image motion velocity oscillations in the telescope focal plane, and also methods developed for terrestrial and in-flight verification of the system.
