SELF-OSCILLATING CONTROL ACTUATOR OF SPIN-STABILIZED GUIDED MISSILE Russian patent published in 2002 - IPC

FIELD: military equipment, guided missiles and projectiles. SUBSTANCE: the self-oscillating control actuator of spin-stabilized guided missile has an adder, whose first input serves as the actuator input and is connected to the output of the missile gyro position indicator, series-connected compensating filter, relay element, power amplifier and a servo unit, whose output serves as the output of the actuator and is connected to the second input of the adder via a feedback element, introduced are series-connected the first product unit and the ripple filter. Introduced are also the second product unit and the scaler, whose output is connected to the additional control input of the relay element, the first input of the first product unit is connected to the adder output, and the second inputs of the product unit are connected to the output of the reference voltage with a phase lead of 90 deg. of the non-controlled amplitude of the gyro position indicator. EFFECT: enhanced dynamic accuracy of follow-up of harmonic input signals by the self- oscillating control actuator of spin-stabilized guided missiles and projectiles. 3 cl, 8 dwg
