    Real-time collision avoidance trajectory planner using generalized vector explicit guidance
    (AIAA, 2023-01-19) Subies Hueso, Josep; Mondal, Sabyasachi; Tsourdos, Antonios; Chadwick, Andrew
    In this paper, a new real-time collision avoidance scheme is proposed using Generalized Vector Explicit Guidance (GENEX) law, an optimal guidance algorithm that can simultaneously achieve design specifications on miss distance and final UAV–target relative orientation. Low computation, closed-form expression, and optimal derivation are the key features that make it a potential candidate for real-time applications. The guidance law has been tested through simulations for the two-dimensional scenario, and the results are very satisfactory.

    Real-time path planning considering static and dynamic obstacles
    (AIAA, 2024-01-04) Subies Hueso, Josep; Mondal, Sabyasachi; Tsourdos, Antonios
    This paper introduces a real-time path planning strategy that effectively navigates around both static and dynamic obstacles. The approach combines the principles of Generalised Explicit Vector (GENEX) and Inverse Proportional Navigation (IPN), established algorithms in missile guidance known for their advantageous features such as low computation and closedform expressions. Leveraging these attributes, the proposed strategy addresses path planning challenges involving static and dynamic obstacles. The performance of the combined algorithm is assessed through a comprehensive simulation study in both 2D and 3D scenarios, considering multiple static and dynamic obstacles.
