Rate limited active pilot inceptor system and method
First Claim
Patent Images
1. An active pilot inceptor system, comprising:
- a pilot inceptor configured to receive user input and, in response to the user input, to (i) move to an inceptor position at an inceptor movement rate and (ii) supply signals representative of a commanded aircraft rate;
a motor coupled to the pilot inceptor and configured, upon being energized, to supply a feedback force to the inceptor that limits at least the inceptor movement rate; and
a motor control configured to receive a rate limit signal that is based on a determined rate error, the rate error being a representative of a difference between the commanded aircraft rate and an actual aircraft rate, the motor control further configured to respond to the rate limit signal to energize the motor to supply the feedback force at a magnitude that limits the inceptor movement rate based on the determined rate error.

Abstract
A variable rate limit is implemented in an active inceptor haptic feedback control system. The rate limit is modulated based on a rate error between an aircraft rate command supplied from the active inceptor, and actual aircraft rate. As the rate error increases, the rate limit is reduced, which limits inceptor movement and provides haptic feedback to a user when the rate error is exceeded.

8. A flight control system, comprising:
-
a flight control configured to receive a signal representative of commanded aircraft rate and a signal representative of actual aircraft rate and, in response these received signals, to determine a rate error and supply a rate limit signal based on the determined rate error; an inceptor configured to receive user input and, in response to the user input, to (i) move to an inceptor position at an inceptor movement rate and (ii) supply the signal representative of commanded aircraft rate; a motor coupled to the inceptor and configured, upon being energized, to supply a feedback force to the inceptor that limits at least the inceptor movement rate; and a motor control coupled to receive the rate limit signal and configured, in response thereto, to energize the motor to supply the feedback force at a magnitude that limits the inceptor movement rate based on the determined rate error. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
