Thrust allocation using optimization in a distributed flight control system
Thrust values for motors in an aircraft are generated where each flight controller in a plurality of flight controllers generates a thrust value for each motor in a plurality of motors using an optimization problem with a single solution. Each flight controller in the plurality of flight controllers passes one of the generated thrust values to a corresponding motor in the plurality of motors, where other generated thrust values for that flight controller terminate at that flight controller. The plurality of motors perform the passed thrust values.
VEHICLE CONTROL LOOPS AND INTERFACES
Embodiments relate to an aircraft control and interface system configured to adaptively control an aircraft according to different flight states by modifying one or more processing control loops. The system receives sensor data from one or more sensors of the aircraft. The system determines, from the sensor data, a component of the aircraft is compromised. The system determines the aircraft is in a degraded flight state due to the compromised component. The system operates the aircraft according to the degraded flight state, wherein operating the aircraft according to the degraded flight state includes: (a) modifying one or more processing loops based on the degraded flight state and (b) generating an actuator command by applying the degraded flight state and a signal based on an input from a vehicle control interface to the modified one or more processing loops.
Integrated feedback to flight computer for adjusting power distribution to rotorcraft motors
A method and system for providing corrective action to a rotorcraft experiencing motor failure is provided. Included in the method and system are embodiments that receive feedback from sensors directed at measuring a state of motors used to provide lift to the rotorcraft. The method and system also describe embodiments for determining that there is a malfunctioning motor, and furthermore, the appropriate corrective action for responding to the malfunctioning motor. In some embodiments, the method and system are configured to reduce power to the malfunctioning motor while simultaneously adjusting power supplied to the remaining motors such that changes in total thrust and net torque are minimized. Further, the method and system are configured to perform diagnostics on the malfunctioning motor while power is still being supplied to the first motor.

Variable condition motor controller
An aerial vehicle, comprising: one or more motors, one or more sensors, and a flight sub-system. The one or more sensors configured to detect data. The flight sub-system includes an attitude controller module; a rate controller module; and a compensator module. The compensator module is configured to: determine a maximum RPM of the one or more motors or a maximum torque of the one or more motors; receive a torque vector from the rate controller module; determine a rotational speed of the one or more motors to generate a desired flight orientation based upon the torque vector; and consider sensor data from the one or more sensors to adjust the rotational speed of the one or more motors.
SITUATIONAL AWARENESS, VEHICLE CONTROL, AND/OR CONTINGENCY PLANNING FOR AIRCRAFT ACTUATOR FAILURE
An aircraft system of an aircraft may, while the aircraft is flying in a first flight mode, receive data from one or more sensors of the aircraft and, based on received data from one or more sensors, identify an actuation failure of an actuator of a flight control surface. The vehicle system may, subsequent to identifying the actuation failure of the actuator of the flight control surface, control the aircraft to fly in a modified flight mode. Controlling the aircraft to fly in the modified flight mode may include: determining a directional bias caused by the actuation failure, determining a modified flight plan based on the determined directional bias, and controlling the aircraft to fly based on the modified flight plan and the directional bias.
