ELECTROPNEUMATIC MISSILE CONTROL ACTUATOR Russian patent published in 2003 - IPC

FIELD: defense equipment, missiles and rockets. SUBSTANCE: the electropneumatic missile control actuator has series-connected set unit, subtraction unit, whose first input serves as the control actuator set input, correcting filter, relay element, power amplifier, control electromagnet and an actuating air motor, whose output serves as the control actuator output and connected via the actuator angle transducer to the second input of the subtraction unit, to the input of the differentiated unit with inversion of the signal, and via an inverter - to the third input of the relay element. The output of the set unit is connected to the fourth input of the relay element, connected in series with the differentiating unit is a non- linear unit with a linear static characteristic with an adjustable dead band, the second input of the non-linear unit is connected to the output of the control actuator angle transducer, and the output - to the second input of the relay element. EFFECT: enhanced damping of the electropneumatic missile control actuator, enhanced quality of the transient process, enhanced precision at following-up of pulse control signals by the control actuator. 3 dwg
