Patent number: 11554881Abstract: This patent presents an attitude determination and control system based on a Quaternion Kalman Filter (QKF) with an extendable number of sensors and actuators. Furthermore, it is compatible with the spherical motor as its attitude actuator. The system includes a processor with a QKF, at least one direct attitude actuator, and at least two environmental sensors. Firstly, system dynamics calculates a first propagation attitude determination result. Next, update the first propagation with the attitude sensor measurements. Then, control the satellite's attitude via the attitude actuator closer to the attitude command provided by the user. The proposed system dynamic model could adjust the number of actuators and sensors freely without reprogramming the algorithms for new missions with new configurations on the actuators and sensors. Moreover, if some components fail, the algorithm can automatically remove those related sequences to avoid the overall failure of the system.Type: GrantFiled: December 8, 2021Date of Patent: January 17, 2023Assignee: TENSOR TECH CO., LTD.Inventors: Po-Hsun Yen, Shang-Jung Lee, Yung-Cheng Chang, Sung-Liang Hou

Patent number: 11506505Abstract: A method for generation of a vehicle path for a vehicle. The method includes, using an excursion planning processor to perform generating a grid of attitude constraint masks, wherein each attitude constraint mask corresponds to a respective possible attitude of the vehicle. The method also includes defining a distance function between two points on a vehicle path, such that the vehicle path defines a change in orientation of the vehicle, determining a vehicle path component, of the vehicle path, between the two points having a selected cost, selecting a vehicle path in the grid of attitude constraint masks from the vehicle path component, and generating an excursion plan so that the vehicle travels along the vehicle path.Type: GrantFiled: February 13, 2019Date of Patent: November 22, 2022Assignee: The Boeing CompanyInventors: Brian K.

Patent number: 11199585Abstract: Diagnosing whether controllers of internal vehicle systems are the source of failures detected by a system control managing a vehicle such as a spacecraft. Highspeed data is received via at a field programmable gate array (FPGA) embedded in an assembly of the vehicle. The FPGA includes a controller and a digital diagnostic interface. In one embodiment, the diagnostic interface utilizes Very Highspeed Integrated Circuit (VHSIC) Hardware Description Language (VHDL) for performance modeling of a controller configured to control at least one internal system within the vehicle. The VHDL performance models the controller. Upon receiving an indication of a failure, the performance modeling of the controller is used to ascertain whether or not the controller is the source of the failure. Disassembly of the assembly housing the internal system is not required in order to ascertain whether or not the controller is the source of the failure.Type: GrantFiled: March 26, 2019Date of Patent: December 14, 2021Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Robert P. Wichowski, Timothy A. Roberts, Darren Woodman, Nicholas Van Derzee

Patent number: 11021248Abstract: A controller system of an aerial vehicle may receive environmental data from one or more sensors of the aerial vehicle and adjusts limits of the aerial vehicle given the environmental conditions. When the aerial vehicle receives an input, such as a flight input from a remote controller or an environmental input such as a gust of wind, the controller system calculates appropriate motor inputs that are provided to the thrust motors of the aerial vehicle such that the adjusted limits of the aerial vehicle are not exceeded. In calculating the appropriate input to the thrust motors, the controller system performs an iterative process. For example, for a given maximum torque that can be applied to the thrust motors, the controller system iteratively allocates the torque such that torque components that are important for the stability of the aerial are first fulfilled, whereas subsequent torque components may be fulfilled or scaled back.Type: GrantFiled: November 4, 2019Date of Patent: June 1, 2021Assignee: GoPro, Inc.Inventors: Joseph Anthony Enke, Benjamin Tankersley, Jean-Bernard Berteaux, Axel Murguet, Garance Bruneau
