FIELD: aerospace engineering. ^ SUBSTANCE: invention relates to systems of supplying electric power to space vehicles with the help of solar batteries (SB). The proposed method includes defining the SB preset mounting angle relative to axes of coordinates related to the space vehicle and measuring angular position of a normal to SB working surface relative to aforesaid axes of coordinates. Angles are measured by the angle pickup to precision of up to some discrete angular sector. According to the invention, the SB angular speed is measured and the designed angle relative to the SB measured angular position is computed in compliance with the time the solar battery intersects the boundary between discrete sectors of the angle pickup at. The aforesaid angle is computed as a product of the SB angular speed be the period of its rotation. SB is rotated in direction of reduced mismatch between preset and computed angles. SB acceleration and braking angles are determined from appropriate aforesaid angles of mismatch. The preset angle is corrected with respect to the measured angular position of the said normal during the moments the angle pickup reading changes by magnitude of one discrete sector. In compliance with the acceleration and braking angles along with the minimum tolerable and maximum possible currents generated by SB, the operation threshold is selected. This threshold exceeded, the mismatch between SB preset and computed angles is formed. Also, the threshold of descent is set up, below which the aforesaid mismatch between SB preset and computed angles deceases. The SB rotation is terminated if the mismatch between SB preset and computed angles increases but not over the operation threshold. ^ EFFECT: increased accuracy of SB preset mounting angle, possibility to control SB position at refusals or failures of angle pickup. ^ 2 dwg |
