This paper presents a weapon target assignment method to reduce maneuverability overload through redistribution for multi-missile cooperative attack. Firstly, a dynamic constrained model of multi-missile cooperative attack on multi-target is established. Secondly, in order to evaluate the missile’s cooperative attack performance better, a cooperative attack probability matrix considering the cooperative attack efficiency is constructed by taking the time-to-go and the line-of-sight rate as *** kinds of maneuvering overload results are compared to verify the effectiveness of redistribution, including unassigned process, primary target assignment and redistribution at the beginning of mid-to-terminal guidance handover. Then, an auction algorithm is used to solve the target assignment problem under multiple constraints. Finally, the simulation results show that the proposed algorithm is much less time-consuming than the existing intelligent optimization algorithms and meets the real-time requirement.

This paper studies the finite-time convergent cooperative guidance problem for multiple missiles to achieve the coordination of the flight time. The control variable is relaxed equivalently and an additional term utilizing the local state information is added such that the finite-time convergence being guaranteed. Furthermore, the time-varying coupling gains are introduced in the guidance law and an algorithm to depict the design process is proposed so that the cooperative guidance law for each follower missile is fully distributed. In addition, finite-time convergence of the guidance error is proved based on Lyapunov theory. Finally, a numerical example is displayed to validate the effectiveness of the proposed theoretical results.

Regarding human-machine collaborative task, generated trajectories of a robot manipulator should be able to avoid joint limits and singularities, but the 6 Degrees of Freedom(DoF) or lower DoF manipulators encounter difficulties in many schemes. In this paper, research is implemented on the methods of trajectory planning and motion control on the newly human-machine collaborative 7-DoF Sawyer manipulator. We try to pay more attention to these approaches and find a better combination between trajectory planners and motion controllers for Sawyer manipulator. First of all, comparison is proposed between the methods about trajectory planning in task space and joint space, drawing a conclusion that the latter has the advantage of quickness and smoothness on trajectories in real time. Next, we choose to plan trajectory in the joint space by interpolating positions and orientations. Three approaches, i.e., trapezoidal velocity trajectory, cubic polynomial trajectory and basic spline trajectory, are applied to interpolate positions. Experimental results show that it results in the smoothest trajectory using basic spline trajectory planning. We also compare linear and nonlinear orientation interpolations to address the angle wrapping issue, which leads to difficulties in smooth orientation interpolation between several waypoints. Combining polynomial trajectory planning methods with the proportional-derivative (PD) motion controller and the computed-torque motion controller, we focus on the performance of the two different combinations. It is found that trajectories with computed-torque controller have shorter path with a congruous convergence on joint position, and more accurate trajectories with less overshoots in position than others. © 2021 IEEE.

The cooperative interception problem of multiple heterogeneous missiles with low maneuverability against highly maneuvering target is studied in this paper. Firstly, the reachable area of the missiles and the escape area of the target are analyzed. The form of the guidance law based on the coverage-based cooperative interception strategy and the standard ballistic design method is given. Secondly, the algorithm for realizing the coverage distribution of multiple heterogeneous missiles is proposed. The parameter design of the cooperative guidance law and the conditions that the initial position of the missiles and target need to meet are derived. Thirdly, the number of heterogeneous missiles required to complete the coverage is calculated by numerical solution. The initial position and the guidance law parameters of each missile are given. Finally, it is verified by simulation examples that multiple heterogeneous missiles with low maneuverability can achieve cooperative interception against highly maneuvering target through the reasonable configuration of the initial interception position and the reasonable design of the cooperative interception guidance law.

Quantum process tomography is a critical task for characterizing the dynamics of quantum systems and achieving precise quantum control. In this paper, we propose a two-stage solution for both trace-preserving and non-trace-preserving quantum process tomography. Utilizing a tensor structure, our algorithm exhibits a computational complexity of O(MLd2) where d is the dimension of the quantum system and M, L represent the numbers of different input states and measurement operators, respectively. We establish an analytical error upper bound and then design the optimal input states and the optimal measurement operators, which are both based on minimizing the error upper bound and maximizing the robustness characterized by the condition number. Numerical examples and testing on IBM quantum devices are presented to demonstrate the performance and efficiency of our algorithm. Copyright © 2024, The Authors. All rights reserved.

The penetration trajectory optimization problem of hypersonic gliding vehicles（HGV） with multiple constraints is investigated. Firstly, the attack-defense confrontation models are established, where the HGV is required to achieve effective penetration under interception missile using Proportional Navigation Guidance（PNG） method. Then the original penetration trajectory optimization problem under multiple constraints is converted into a second-order cone programming（SOCP） problem through linearization, discretization and convexification manipulation. The online sequential convex optimization algorithm is used to solve the SOCP problem. Finally, numerical simulations are given to demonstrate the effectiveness of the method and penetration effect.

Neural networks based on interval-valued pseudo overlap and grouping functions with applications to fuzzy reasoning and image classification

Pseudo overlap functions (POFs) are critical in image processing, text classification, decision-making systems etc. However, integrating interval-valued pseudo overlap functions (IPOFs) and interval-valued pseudo grouping functions (IPGFs) with neural networks remains underexplored. To address this gap, we propose a systematic framework that fundamentally redesigns neural architectures using IPOFs and IPGFs. First, some new results about IPOFs and IPGFs are introduced, including their pseudo automorphisms, multiplicative generators and additive generators. Then, ANNs and CNNs based on IPOFs (called IV-POG ANNs and IV-POG CNNs) are introduced respectively. The introduction of IPOFs substantially enhance the nonlinearity, asymmetry and bilateral approximation ability of ANNs and CNNs. Third, Takagi–Sugeno–Kang (TSK) fuzzy systems based on IPOFs are introduced and IV-POG ANNs are used to fit these systems and train their parameters. The experiments demonstrate that IPOFs significantly enhance the image classification performance of ANNs and CNNs, while simultaneously strengthening the inference capabilities of TSK fuzzy systems.

UK hung parliament (UKHP) prediction is a concern. It may not only cause political issues, but also lead to troubles in other fields such as economics. It is important to make predictions on UKHP. In this paper, we use three-variable and five-variable Weng-Zhang algorithms (also termed addition-subtraction and frequency [ASF] algorithms) of different traversal types to predict the risky time-intervals and years of UKHP to give an early alert for avoidance. Experiment results show that 2021-2023, 2047-2068, and 2098-2104 are more potentially risky, and 2023, 2053, 2055, 2061, 2068, and 2098 have a greater risk for the occurrence of UKHP. © 2021 IEEE

The work presented in this paper focuses on the finite-time control of the master-slave manipulators with time-varying delay. First, a nonsingular fast terminal sliding mode control (NFTSMC) is used for this system based on the knowledge of the upper bound of the uncertainties and disturbances. Despite of the presence of the uncertainties, disturbances, load variation and time-varying delay, the controller is robust and present a finite-time convergence. Second, an adaptive nonsingular fast terminal sliding mode control (ANFTSMC) is applied to master-slave manipulators to avoid the knowledge of the upper bound of the uncertainties and disturbances. This controller presents good performance compared to the first one. The two controllers are evaluated in simulation.
