FBW ROTORCRAFT CONTROL WITH REDUNDANT PROCESSORS USING STATE COMPARISON
A control system and method for providing state comparison of redundant processors used to control a rotorcraft (101). A primary microprocessor (412) is configured to receive input data from a position sensor (207) and a flight condition sensor (207) and to determine therefrom a first desired contro...

| Zusammenfassung: | A control system and method for providing state comparison of redundant processors used to control a rotorcraft (101). A primary microprocessor (412) is configured to receive input data from a position sensor (207) and a flight condition sensor (207) and to determine therefrom a first desired control law state, and a secondary microprocessor (414) is configured to receive input data from the position sensor (207) and the flight condition sensor (207) and to determine therefrom a second desired control law state.
The first desired control law state from the primary microprocessor (412) and the second desired control law state from the secondary microprocessor (414) are compared, and either (a) the first desired control law state is taken into accont when the first desired control law state and the second desired control law state match, or (b) a last known control law state is maintained when the first desired control law state and the second desired control law state do not match. |
