SELF-OSCILLATING CONTROL ACTUATOR OF ROLL-STABILIZED GUIDED MISSILE Russian patent published in 2006 - IPC F42B15/01 B64C13/36 

FIELD: defensive equipment, in particular, guided missiles and rockets.

SUBSTANCE: the self-oscillating control actuator of a roll-stabilized missile has an adder, whose first input serves as the input of the actuator, series-connected correcting filter, relay element, power amplifier and an actuator, whose output serves as the actuator output and is connected via a feedback element to the second input of the adder, in addition use is made of a series-connected differentiator and a nonlinear element, having a linear static characteristic with a dead zone, whose magnitude reduced to the actuator input at the missile rotational speed equals the linear element of the actuator output co-ordinate. The differentiator input is connected to the actuator input, and the nonlinear element output - to the additional control input of the relay element.

EFFECT: enhanced dynamic accuracy of the self-oscillating control actuator of roll-stabilized guided missile at a response to the sinusoidal signal of the missile rotational frequency with an amplitude corresponding to the limiting of the actuator output co-ordinate.
