Abstract :
Some problems on a nonius (vernier) guidance, robust attitude control and long-time image motion 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, are presented.
