Three-dimensional Multi-missile Cooperative Guidance Law with Time and Space Constraints
Jian Meng,Zhen Yang,Jichuan Huang,Haiyin Piao,Yiyang Zhao,Deyun Zhou 제어로봇시스템학회 2022 제어로봇시스템학회 국제학술대회 논문집 Vol.2022 No.11
This study focuses on the problem of multiple air-to-air missiles coordinated intercepting maneuvering targets in three-dimensional (3-D) space. A fixed time cooperative interception law with attack time and line-of-sight (LOS) angle limitations is proposed. Firstly, we extended the commonly used two-dimensional (2-D) space guidance model to 3-D space, and constructs a 3-D missile-target relative motion model. Secondly, the missile guidance model is decoupled to along and perpendicular to the LOS, and in the LOS direction, a cooperative guiding law based on fixed-time consistency theory is intended to guarantee that all missiles strikes the target at the same moment. Moreover, in the LOS normal direction, an adaptive approach rule is created, and the LOS angle of each missile is regulated to reaching to a given value in a defined time. According to the proposed fixed time fast non-singular terminal sliding mode surface, and spatial coordination is accomplished. In addition, based on Lyapunov stability theory, a detailed fixed time stability analysis is given. In the end, simulation is used to verify the feasibility and efficacy of the guideline law.

Generation Method of Autonomous Evasive Maneuver Strategy in Air Combat
Lin Li,Zhen Yang,Zhixiao Sun,Guang Zhan,Haiyin Piao,Deyun Zhou 제어로봇시스템학회 2022 제어로봇시스템학회 국제학술대회 논문집 Vol.2022 No.11
Air combat is usually a continuous process involving multiple rounds of missile attacks, UCAV(Unmanned Combat Aerial Vehicle) should consider the impact of maneuver on the entire air combat countermeasure mission rather than solely focusing on safety factors when evading incoming air to air missiles. In this paper, a method of generating autonomous evasive maneuver strategy in UCAV air combat is proposed under the condition of miss distance and energy dissipation. Firstly, the UCAV-missile three-dimensional space pursuit model and the UCAV autonomous evading state space, action space and reward function model are established. Dueling DDQN (Double Deep Q Network) algorithm is used to solve the model, which integrates Double DQN and Dueling DQN Network model. Simulation experiments and analysis show that the method proposed in this paper has significant effectiveness in solving the problem of autonomous evasive maneuvers in air combat under the conditions of miss distance and energy dissipation tactical requirements. The evasive maneuvers strategy obtained can reflect the two tactical requirements of air combat while ensuring the safety of UCAV itself.
