METHOD OF CONTROL OVER SPACECRAFT SOLAR BATTERY WITH PROTECTION AGAINST SHORT-TERM FAULTS OF DATA ON SOLAR BATTERY ANGULAR BATTERY Russian patent published in 2014 - IPC B64G1/44 

FIELD: transport.

SUBSTANCE: invention relates to spacecraft electric power supply with the help of solar batteries. Proposed method consists in definition of preset angle of solar battery, measurement of its current angle and computation of design angle by angular velocity and spinning time. Solar battery acceleration angle (α_AC) and deceleration angle (α_DEC) are defined. Solar battery is spinned to threshold of drop-away (α_DROP ≈ (α_DEC) when mismatch between said preset and design angles is terminated. Before start of the control, preset angle is memorised to take initial preset angle as valid actual current angle. Mismatch threshold (α_THR) of said angles proceeding from angles α_AC and α_DEC, as well as minimum tolerable currents of solar battery. Angle transducer circle is divided into equal discrete sectors by magnitude a given the condition α_AC + α_DEC < σ < α_THR. Discrete sector bisectors are taken to be measured magnitudes. Period of valid current angle definition is set to the order and exceeding maximum duration of transducer data fault and smaller than minimum interval of faults train. Said interval is divided to four equal interval while analysis of measured and memorised magnitudes in said intervals are reset to generate validity signal. In the latter case, solar battery is spinned to mismatch between design and preset angles α_DROP to set new preset angle magnitude.

EFFECT: higher survivability and efficiency.
