Abstract
A piloting device for piloting an aircraft includes a first and a second control stick movably mounted on a support, a detection system for detecting the positions of the first and second control sticks, an elastic mechanism configured to apply a restoring force to the second control stick, first and second actuation systems configured to apply respective first and second position adjustment forces to the respective first and second control sticks, and a control module configured to control the second adjustment force so that the positions of the first and second control sticks are identical. The control module is configured to control the first adjustment force based on the second adjustment force and the restoring force.
Claims12
A piloting device for piloting an aircraft comprising a first control stick and a second control stick, each movably mounted on a support between a plurality of positions around a neutral position in at least one degree of freedom,
- the piloting device further comprising:
- a detection system for detecting the position of the first control stick and second control stick, configured to generate first position data representing the position of the first control stick and second position data representing the position of the second control stick;
- a first elastic mechanism configured to apply a first restoring force to the first control stick, toward its neutral position;
- a second elastic mechanism configured to apply a second restoring force to the second control stick, toward its neutral position;
- a first actuation system configured to apply a first position adjustment force to the first control stick, according to each degree of freedom;
- a second actuation system configured to apply a second position adjustment force to the second control stick, according to each degree of freedom;
- a control module configured to control the second position adjustment force based on the position data of the first control stick so that the position of the first control stick in relation to its neutral position and the position of the second control stick in relation to its neutral position are identical;
- wherein the control module is further configured to control the first position adjustment force based on the second position adjustment force and the second restoring force,
- wherein the second position adjustment force depends on a control force applied to the second control stick by an aircraft crew member,
- wherein the control module is configured to calculate the control force applied to the second control stick, the control force being equal to the second position adjustment force minus the second restoring force,
- wherein the first position adjustment force depends on the control force applied to the second control stick,
- wherein the first position adjustment force is equal to the control force applied to the second control stick.

- wherein the control module is further configured to control the first position adjustment force based on the second position adjustment force and the second restoring force,
- wherein the second position adjustment force depends on a control force applied to the second control stick by an aircraft crew member,
- wherein the control module is configured to calculate the control force applied to the second control stick, the control force being equal to the second position adjustment force minus the second restoring force,
- wherein the first position adjustment force depends on the control force applied to the second control stick,
- wherein the first position adjustment force is equal to the control force multiplied by a correction coefficient,
- wherein the correction coefficient compensates for an asymmetry between roll restoring force profiles of the first and second elastic mechanisms.
