Abstract

A system for flight control in electric aircraft includes a flight controller configured to provide an initial vehicle torque signal including a plurality of attitude commands. The system includes a mixer configured to receive the initial vehicle torque signal and a vehicle torque limit, receive prioritization data including a prioritization datum corresponding to each of the plurality of attitude command, determine a plurality of modified attitude commands as a function of the vehicle torque limit, the attitude commands, and the prioritization data, generate, as a function of modified attitude commands, an output torque command including the initial vehicle torque signal adjusted as a function of the vehicle torque limit, generate, as a function of the output torque command, a remaining vehicle torque. The system includes a display, wherein the display is configured to present, to a user, the remaining vehicle torque and the output torque command.

Claims (37)

1. A system for flight control in electric aircraft, the system comprising:

a flight controller, wherein the flight controller is configured to provide an initial vehicle torque signal comprising a plurality of attitude commands;

a mixer, wherein the mixer includes circuitry configured to:

receive the initial vehicle torque signal;

receive at least a vehicle torque limit;

receive a plurality of prioritization data, the plurality of prioritization data including a prioritization datum corresponding to each of the plurality of attitude commands;

determine a plurality of modified attitude commands as a function of the at least a vehicle torque limit, the plurality of attitude commands, and the plurality of prioritization data;

generate, as a function of the plurality of modified attitude commands, an output torque command, wherein the output torque command includes the initial vehicle torque signal adjusted as a function of the at least a vehicle torque limit; and

generate, as a function of the output torque command, a remaining vehicle torque.

2. The system of claim 1 , wherein the mixer comprises an inertia compensator.

3. The system of claim 2 , wherein the inertia compensator comprises a lead filter.

4. The system of claim 1 , wherein the mixer is implemented using an electrical logic circuit.

5. The system of claim 1 , wherein the mixer is implemented using a processor.

6. The system of claim 1 , wherein the flight controller is a proportional-integral-derivative (PID) controller.

7. The system of claim 1 , wherein the flight controller is configured to provide the initial vehicle torque signal as a function of a control algorithm.

8. The system of claim 1 wherein the flight controller is configured to provide the initial vehicle torque signal as a function of an autonomous function.

9. The system of claim 1 , wherein the remaining vehicle torque comprises the remaining vehicle torque capability in an aircraft's pitch moment.

10. The system of claim 1 , wherein the remaining vehicle torque comprises the remaining vehicle torque capability in an aircraft's roll moment.

11. A method for flight control in electric aircraft, the method comprising:

providing, at a flight controller, an initial vehicle torque signal comprising at least an attitude command;

receiving, at a mixer, the initial vehicle torque signal including a plurality of attitude commands;

receiving, at the mixer, at least a vehicle torque limit;

receiving, at the mixer, a plurality of prioritization data including a prioritization datum corresponding to each of the plurality of attitude commands;

determining, at the mixer, a plurality of modified attitude commands as a function of the at least a vehicle torque limit, the plurality of attitude commands, and the plurality of prioritization data;

generating, at the mixer, as a function of the plurality of modified attitude commands, an output torque command, wherein the output torque command includes the initial vehicle torque signal adjusted as a function of the at least a vehicle torque limit; and

generating, at the mixer, as a function of the output torque command, a remaining vehicle torque.

12. The method of claim 11 , wherein the mixer comprises an inertia compensator.

13. The method of claim 12 , wherein the inertia compensator comprises a lead filter.

14. The method of claim 11 , wherein the mixer is implemented using an electrical logic circuit.

15. The method of claim 11 , wherein the mixer is implemented using a processor.

16. The method of claim 11 , wherein the flight controller is a proportional-integral-derivative (PID) controller.

17. The method of claim 11 , wherein providing the initial vehicle torque signal further comprises:

providing, using the flight controller, the initial vehicle torque signal as a function of a control algorithm.

18. The method of claim 11 , wherein providing the initial vehicle torque signal further comprises:

providing, using the flight controller, the initial vehicle torque signal as a function of an autonomous function.

19. The method of claim 11 , wherein the remaining vehicle torque comprises the remaining vehicle torque capability in an aircraft's yaw moment.

20. The method of claim 11 , wherein the remaining vehicle torque comprises the remaining vehicle torque capability in an aircraft's assisted lift.
