High-precision control of the observation satellite with small power consumption

An unified method of the control, orientation and stabilization is proposed; the method allows an observation satellite (OS) to be brought in the sliding mode with a specified accuracy and in a required time to the necessary angular terminal position in the conditions of the limited indefinite external disturbances. The method minimizes power consumption for control. An approach for regulation of the frequency and amplitude of steady-state control oscillations is presented.
