SELF-OSCILLATING CONTROL ACTUATOR OF GUIDED MISSILE Russian patent published in 1997 - IPC

FIELD: defence equipment, guided missiles. SUBSTANCE: self-oscillating control actuator of guided missile uses an adder, whose first input serves as the actuator input, series-connected relay element, power amplifier and a servo unit, whose output serves as the actuator output and is connected via a feedback element to the adder second input; a correcting filter of the differentiating type with a predominance of integration at free-running frequencies is introduced. The filter is a chain of series-connected resistor and capacitor, which is cut in between the input of the relay element and common bus; the adder is built around three resistors, the first leads of the two of them are connected to the first and second inputs of the adder, and the second leads are connected to the first lead of the third resistor connected in parallel with the chain of series - connected resistor and capacitor of the correcting filter; the resistances of the third resistor and resistor of the correcting filter are the same. EFFECT: enhanced precision of control actuator operation and simplified circuitry. 1 dwg
