Abstract
The invention relates to a method of managing a steering control for a steerable portion of an aircraft undercarriage, the method comprising implementing servo-control to servo-control an electromechanical steering actuator on an angular position setpoint, wherein, according to the invention, the servo-control implements a control relationship H∞ type, the position and speed information being delivered by means of a fieldbus of deterministic type to a computer that implements the servo-control.
Claims4
A method of managing steering control of a steerable portion of an aircraft undercarriage, having an electromechanical steering actuator and using a reference model established for control of the undercarriage and steering actuator, a control synthesizer that synthesizes H∞ (H-infinity) control, weighting filters, a servo control system, and an optimizer algorithm that modifies parameters of the weighting filters to cause the servo control system to respond closely to the reference model, the method comprising:
- implementing servo-control of the electromechanical steering actuator on an angular position setpoint,
- wherein the servo-control implements a robust control relationship of the H∞ (H-infinity) type,
- wherein position and speed information needed for implementing the servo-control are delivered by means of a fieldbus of deterministic type to a computer that executes that implementation, and
- wherein the H∞ control is synthesized automatically by means of the optimization algorithm that determines the parameters of the weighting filters of the control relationship,
- whereby the response of the steering control as servo-controlled in this way complies with a response of the reference model.
