Precise Stabilization of Optical Image at a Space Astronomical Telescope by a Fine Piezo-driver with Physical Hysteresis
Yevgeny Somov, Sergey Butyrin, Sergey Somov
Some problems on a nonius guidance, robust attitude control and long-time image stabilization of a large space astronomical telescope are considered. Elaborated methods
for dynamic research under external and parametric disturbances, partial discrete measurement of the state, digital control of the gyro moment cluster and a fine piezo-driver with physical hysteresis, are presented.
