SELF-EXCITED ACTUATOR OF GUIDED MISSILE ROTATING IN ROLL Russian patent published in 2004 - IPC

FIELD: defense equipment; guided missiles and projectiles.

SUBSTANCE: proposed actuator includes first adder whose first input is used as input of actuator and is connected to output of gyro-coordinator of missile, correcting filter, relay unit, power amplifier and servo unit whose output is used as output of actuator, unit for conversion of angle of turn of control surfaces into feedback signal; it is connected with second input of first adder; actuator includes also the following components connected in series: first product unit, first ripple filter, second product unit and first scaler whose output is connected with additional control input of relay unit; first input of first product unit is connected to output of first adder and second inputs of first and second product units are connected with output of reference voltage at phase lead of 90 deg. of non-adjustable amplitude of gyro-coordinator; provision is additionally made for third product unit, second ripple filter, two branches connected in parallel; first branch is provided with first half-wave rectifier of negative half-wave and second scaler connected in series; second branch includes second half-wave rectifier of positive half-wave, third scaler and inverter connected in series; outputs of said branches are connected to inputs of second adder whose output is connected to first input of fourth product unit whose second input is connected to output of missile gyro-coordinator and output is connected to third input of first adder; first input of third product unit is connected to output of first adder and second input is connected to reference voltage output of non-adjustable amplitude of gyro-coordinator.

EFFECT: enhanced dynamic accuracy of control of harmonic input signals.
