SELF-SUSTAINED CONTROL ACTUATOR OF GUIDED MISSILE Russian patent published in 1998 - IPC

FIELD: defence equipment, in particular, guided missiles. SUBSTANCE: control actuator 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 second input of the adder; it also uses an intergrodifferentiating-type correcting filter with amplitude attenuation and phase lead at free-running frequencies made in the form of series-connected operational amplifier, whose forward circuit incorporates the first and second resistors, whose first leads are connected respectively to the actuator input and feedback element output, and the third resistor - in the feedback circuit connected in parallel with which is a chain of series-connected fourth resistor and integrating capacitor, and a chain of parallel-connected fifth resistor and differentiating capacitor, whose output via the sixth resistor is connected to the inverting input of the relay element and to the chain of parallel-connected seventh resistor and capacitor, whose second lead is connected to the common bus. EFFECT: enhanced accuracy of operation and enhanced free-running frequency. 3 dwg
