In this paper, a distributed cooperative tracking algorithm is proposed for the small patrol UA V target tracking problem. By setting up a sensor network to realize the communication between missile clusters, we introduce a weighted information fusion and distribution method for multiple sensor nodes. Meanwhile, a trajectory shaping guidance law is derived for the three-dimensional space maneuver target striking problem. In the scenario of multi-missile UA V target interception, the simulation of multi-missile tracking and the striking process is completed to achieve accurate estimation of target position, velocity, and acceleration. The effectiveness and superiority of this cooperative tracking algorithm are verified through extensive simulations and comparisons. © 2023 Technical Committee on control Theory, Chinese Association of automation.

The capacity of software to adapt its functionalities based on user preferences or hardware requirements is of utmost importance. Improved user satisfaction and overall system performance are just two of the advantages. Kernel configuration serves as a practical example. Situated at the core of an operating system, the kernel is responsible for critical tasks such as process management and memory allocation. Its configuration process has naturally evolved to address the needs of users and systems, as well as specific hardware requirements. However, given the complexity of such projects, the entire configuration process can quickly become overwhelming, especially for users unfamiliar with kernel internals. This paper introduces a 32-bit kernel with a more user-friendly configuration process, facilitated by a step-by-step configuration menu and default configuration profiles. The kernel implements essential features such as file system support, a syscall interface, process control, and physical and virtual memory management. © 2024 IEEE.

Aninfinite-dimensional nonlinear model for a two-degree-of-freedom highly flexible wing is presented in this paper. The model describes the coupled dynamics of bending and torsion in terms of a set of nonlinear partial differential equations. When torsion is ignored, the resulting transverse bending equations are identical to those for the well-known elastica. The in vacuo response and the flutter onset characteristics of the model are compared with standard aeroelastic models using numerical simulation. The nonlinear model presented here could potentially serve as a benchmark for PDE-based control design methods, providing an intermediate step between low-fidelity linear models and nonlinear simulation models whose high fidelity is usually accompanied by large computational times. © 2025, American institute of Aeronautics and Astronautics Inc, AIAA.

This paper presents a novel VTOL UAV that owns a link connecting four rotors and a fuselage by a passive joint, allowing the control of the rotor's tilting angle by adjusting only the rotors' thrust. This unique structure contributes to eliminating additional actuators, such as servo motors, to control the tilting angles of rotors, resulting in the UAV's weight lighter and simpler structure. We first derive the dynamical model of the newly designed UAV and analyze its controllability. Then, we design the controller that leverages the tiltable link with four rotors to accelerate the UAV while suppressing a deviation of the UAV's angle of attack from the desired value to restrain the change of the aerodynamic force. Finally, the validity of the proposed control strategy is evaluated in simulation study.

This paper proposes a novel hybrid UAV that can turn acutely with flip-turn motion. The UAV has a link consisting of four rotors, named quadlink, which is connected to the fuselage via a passive joint. When the UAV wants to turn in the reverse direction, only the quadlink rotates to generate thrust in the reverse direction for deceleration without changing the attitude of the wings. This eliminates the vertical motion during the deceleration of the conventional tailsitter UAVs and achieves acute turning. Then, once the UAV sufficiently slows down, it accelerates in the reverse direction while flipping the fuselage upside down to point the nose in the reverse direction. Finally, the UAV fully transitions to reverse cruise flight in the opposite direction. This paper only considers longitudinal motion as the first step in controlling the proposed UAV. The acute turn is accomplished without switching controllers. The paper finally presents a simulation result to evaluate the performance of the proposed UAV and controller.

The three single-phase combined (TSC) topology has been ruling the power converter industries for many years. In this research, TSC topology with Lithium Battery DC source is proposed for 400Hz Ground Power Unit (GPU) due to its advantages particularly in increasing the system flexibility and reliability. Sinusoidal Pulse Width Modulation (SPWM) is one of the most viable PWM techniques for inverter, however, it is shown that SPWM has no good contribution on three phase control system, hence, Space Vector Modulation (SVM) technique is now more widely used. This paper proposes a novel effectual three-dimensional Space Vector Modulation (3D-SVM) technique for three single-phase combined inverter, which can provide up to 27 switching states, expanding the possible range to find the best decision boundary to compare with traditional SPWM. The effectiveness of the proposed method is verified through MATLAB simulations. © 2023 IEEE.
