Jack servo-controlled in position in order to control the flight of an helicopter.

摘要

Jack servo-controlled in position for control of the helicopter flight, comprising a motor (m) supplied by a circuit (100) controlled by an error signal (e), a sensor of the output (cs) giving an indication of the position of the jack, and a circuit for computing the error signal comparing a desired position (pc) of the jack to a calculated position (p). br / according to the invention, said sensor of the output (cs) provides a signal (cs) of taking two different values according to the position of the jack with respect to a mid-point, said signal (cs) of the position being applied to a circuit (500) for putting under a voltage which switches the input of the circuit (100) on the sensor of the output (cs) so as to apply the signal (cs) of the position of the circuit (100) up to the change of value of the binary signal of position, the circuit (500) of turning on switch then the input of the circuit (100) on the output of circuit (200) of calculation of the error signal (e), the position calculated (pc) of the jack being provided by a circuit (400) receiving a signal (cm) of the position - motor from a sensor located on the motor (m). br / application to the control of a helicopter in the automatic piloting.
