高超声速目标拦截中的多飞行器协同制导控制理论与方法

The background of this project is the intercept problem of the hypersonic target in the near space. The purpose is to investigate the coordination control theory and methodology of multiple flight vehicles. First, considering the complicated detective atmosphere in the near space, the super high velocity and maneuverability of the hypersonic target, the uncertainties of the target caused by the detection are descried as a target motion region with some certain distribution in which the target moves based on the coordinated information detected via multiple flight vehicles. Moreover, a non-uniform assignment approach of the target motion region will be proposed to assign each flight vehicle a sub-region. Secondly, the hybrid dynamical game theory and dynamical coverage control of multiple agents will be investigated focusing on the guidance control problems proposed. Thirdly, aiming against the possible maneuver types of the hypersonic target, the guidance strategy will be proposed based on the hybrid dynamical game theory for the multiple flight vehicles intercepting a hypersonic target. Then, in terms of the distribution of the sub-region assigned to each flight vehicle, a guidance law design approach will be proposed based on the dynamical coverage control of multiple agents in order to solve a special “point-to-region” guidance problem. Last, the target motion region model of the hypersonic target will be verified in terms of the flight experimental data; moreover we will set up a hard-ware-in-the loop simulation platform, by which the experiment verification will be achieved for the effectiveness of the proposed guidance strategy and the guidance law design methodologies, and the feasibility of the guidance algorithm. The aim of our project is to provide a sound theoretical foundation and design approaches for the practical application.
