Abstract:
1. A method of determining the static force developed by a servo-control having an actuator and a hydraulic distributor control valve, said actuator comprising at least one cylinder defining an inside space and a slidable element provided with a control piston slidable in said inside space, said hydraulic distributor control valve feeding said inside space with a fluid, and the method comprising the following steps: determining an instantaneous travel speed of said slidable element relative to said cylinder of the servo-control; and determining said static force with the help of: where F represents an instantaneous static force developed by the servo-control, F max represents a predetermined maximum static force that can be developed by the servo-control, V 2 represents the measured instantaneous travel speed of said slidable element raised to the second power, V 2 max represents a maximum travel speed of said slidable element relative to said cylinder raised to the second power, and * represents the multiplication sign.
