When any one of a plurality of first rotors (VTOL rotors) fails, a rotor controller (a VTOL rotor controller) executes thrust increase control for increasing the thrust generated by an adjacent first rotor that is the first rotor adjacent to the failed first rotor, without making the adjacent first rotor cause the thrust variation for vibration suppression control, and executes the vibration suppression control in a manner so that one or more second rotors (VTOL rotors) bear the burden of the thrust variation that has been borne by the adjacent first rotor.

This disclosure relates to apparatuses, systems, and methods for handling faults on vehicles. One or more processors in a vehicle may receive, from a control unit in response to a detection of a fault in the vehicle, an indication of a degradation in a performance constraint of the vehicle. The processors may determine, responsive to the degradation in the performance constraint, that the vehicle is unable to execute a set of commands to control a movement of the vehicle along a trajectory. The processors may generate, in accordance with the degradation in the performance constraint, a modified set of commands that the vehicle is able to execute to control the movement of the vehicle along at least a portion of one or more trajectories. The processors may provide the modified set of commands to the control unit of the vehicle to control the movement of the vehicle.

A system, computer readable storage medium and method for controlling a trajectory of coordinated time-varying maneuvers of a geometric formation of unmanned vehicles is disclosed. The system includes unmanned vehicles, each configured with communication circuitry to communicate between the vehicles. A subset of the unmanned vehicles function as leader vehicles, with the remaining vehicles functioning as follower vehicles for leader-follower maneuvering. The system further includes an actuator suite configured to adjust the direction and orientation of each vehicle, a sensor suite for stabilization and navigation, and a flight controller for maintaining stable maneuvering, even in the presence of actuator faults and sensor deception attacks. Processing circuitry is configured with a reinforcement learning neural network that includes identifier, actor, and critic radial basis function neural networks to estimate movement, adjust control actions, and assess vehicle performance based on feedback signals, including corrupted signals from the sensor suite due to deception attacks.

Utility vehicles with battery management and autonomous control systems are disclosed. A utility vehicle includes driven wheels, electric motor(s), blade motor(s), at least one battery, battery management system(s), global navigation satellite system receiver(s), and controller(s) communicatively connected to memory. The controller(s) identify whether map data for a mow area is stored in the memory and perform a sparse-mow routine in response to identifying no map data in the memory. To perform the sparse-mow routine, the controller(s) autonomously steer the electric utility vehicle to travel over a sample of each portion of the mow area, collect location data, and collect current discharge data. The controller(s) generate an energy-consumption map for the mow area by correlating the current discharge data with the location data and determine an efficient-mow path for subsequent mowing events of the mow area based on the energy-consumption map.

A hybrid-electric propulsion system includes a propulsor, a turbomachine, and an electrical system having an electric machine coupled to the turbomachine. A method for operating the propulsion system includes operating, by one or more computing devices, the turbomachine to rotate the propulsor and generate thrust for the aircraft; receiving, by the one or more computing devices, data indicative of an un-commanded loss of the thrust generated from the turbomachine rotating the propulsor; and providing, by the one or more computing devices, electrical power to the electric machine to add power to the turbomachine, the propulsor, or both in response to receiving the data indicative of the un-commanded loss of thrust.

An automatic watercraft maneuvering system includes a propulsion device, a steering, a position sensor, a camera, and a controller configured or programmed to execute an automatic watercraft maneuvering control to control the propulsion device and the steering in order to perform automatic watercraft maneuvering from a departure location to a destination location. The automatic watercraft maneuvering control includes a camera watercraft maneuvering control and a position sensor watercraft maneuvering control. The controller is configured or programmed to, when a failure occurs in the position sensor in a predetermined area of water in which the automatic watercraft maneuvering is executable using the camera watercraft maneuvering control, cause the watercraft to head to a predetermined target position in the predetermined area of water in which the failure occurs during the camera watercraft maneuvering control.

Provided is a reception device comprising: a reception part configured to receive the control signal from a transmission device; and a controller configured to performs a process of outputting a motor driving instruction value corresponding to the control signal received by the reception part as a motor driving instruction value for controlling a driving amount of a motor, wherein the controller performs: a hold process for holding and outputting a value corresponding to the control signal during a reception period as the motor driving instruction value when the control signal is not receivable; and a failsafe gradual change process for gradually changing the motor driving instruction value from the value during the hold process toward a failsafe value determined for failsafe when a period of the hold process reaches a certain period.
