Publication number: 20240136946Abstract: This patent presents a multidimensional space vector modulation (MDSVM) circuit formed by coupling a half-bridge logic control circuit not directly coupled to electronic components with at least three half-bridge logic control circuits coupled to electronic components. The half-bridge logic control circuit not directly coupled with any electronic components can form a full-bridge circuit with any other half-bridge logic control circuit coupled with electronic components. Therefore, users can further control the voltage difference between both ends of each electronic component separately and then individually control the strength and direction of current flowing through each electronic component and solving the problem of control attributed to the complexity of prior art.Type: ApplicationFiled: April 10, 2023Publication date: April 25, 2024Applicant: TENSOR TECH CO., LTDInventors: Shang Jung LEE, Po-Hsun YEN, Yung-Cheng CHANG, Sung-Liang HOU

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
