Abstract
The invention relates to a servo-control device comprising at least one servo-control loop which receives a servo-control signal as input and whose output acts on an element to be servo-controlled, said device comprising means for determining a parameter characterizing the real force generated by the servo-control, the device also including a loop having means for determining an error characteristic of the difference between said parameter characterizing the real force and a parameter characterizing an acceptable theoretical force which is a function of the servo-control signal, and also means for correcting the processing of the servo-control loop as a function of said error. The means for determining the error make use of a reference model which is advantageously a transfer function relating force to a flow rate control signal.
