Abstract
A system for fault detection and control in an electric aircraft including an inertial measurement unit, the inertial measurement unit including at least a sensor configured to detect a torque datum associated with at least a propulsor. The system includes an observer, the observer configured to generate a torque prediction datum associated with the at least a propulsor, compare the torque prediction datum with the torque datum, and generate a residual datum as a function of the comparison. The system includes a mixer, the mixer comprising circuitry configured to generate, as a function of the residual datum, a torque priority command datum and transmit, to the at least a propulsor, the torque priority command datum.
Claims20
A method comprising:
- determining that sensor data associated with a first propulsor of a plurality of propulsors for a vehicle satisfies at least one criterion associated with a command to alter a trajectory of the vehicle;
- and
- in response to receiving the command to alter the trajectory of the vehicle and determining that the sensor data associated with the first propulsor satisfies the at least one criterion, switching from a first control allocation to control the plurality of propulsors to a second control allocation to control the plurality of propulsors, the first control allocation differing from the second control allocation for the command.
A system comprising:
- a sensor configured to detect sensor data associated with a first propulsor of a plurality of propulsors configured to propel a vehicle;
- and
- a controller configured to:
- determine that the first propulsor is in a failure state based on the sensor data satisfying at least one criterion associated with a command to alter a trajectory of the vehicle;
- and
- in response to receiving the command to alter the trajectory of the vehicle and determining that the first propulsor is in the failure state, switch from a first control allocation to control the plurality of propulsors to a second control allocation to control the plurality of propulsors, the first control allocation differing from the second control allocation for the command.
A system comprising:
- a non-transitory machine-readable storage medium;
- at least one processor operatively coupled to the non-transitory machine-readable storage medium;
- and
- instructions stored on the non-transitory machine-readable storage medium that, when executed by the at least one processor, direct the at least one processor to perform a method, the method comprising:
- determining that sensor data associated with a first propulsor of a plurality of propulsors for a vehicle satisfies at least one criterion associated with a command to alter a trajectory of the vehicle;
- and
- in response to receiving the command to alter the trajectory of the vehicle and determining that the sensor data associated with the first propulsor satisfies the at least one criterion, switching from a first control allocation to control the plurality of propulsors to a second control allocation to control the plurality of propulsors, the first control allocation differing from the second control allocation for the command.
