SPACECRAFT TURN CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: automatic control of non-stationary space objects. SUBSTANCE: proposed control system is used for turn of spacecraft to required attitude position. Control system includes control engine unit and setters for setting required angle of turn, permissible angular velocity and minimum acceleration, as well as modulus determination unit, multipliers and computer unit. Provision is also made for selection of minimum signal of spacecraft angular velocity , memory, forming of preset angular velocity and setting of time of turn; system includes also functional amplifier, non-linear gate, etc. Control system optimizes transient processes in speed of response under conditions of high degree of instability of control engine efficiency and parameters of spacecraft due to failure of these engines, change in mass of spacecraft at burning-out of propellant in main cruise engine, etc. EFFECT: reduced consumption of propellant; optimal speed of response of spacecraft. 3 cl, 7 dwg
