Research Status and Prospects of Constrained Cooperative Guidance: A Review

Cooperative guidance enables multiple flight vehicles to achieve various objectives through information sharing. Constraints are inevitable and pose new threats to cooperative safety, presenting formidable challenges to cooperative guidance technology. This study aims to sort out and analyze the research lineage and development trend of constrained cooperative guidance. First, a bibliometric analysis is conducted on the Scopus database. The development trajectory and research hotspots are analyzed by CiteSpace visualization. Then, the preliminaries of cooperative guidance law are provided. Based on the discussion of classical and co-cited references, the research on cooperative guidance is performed with constraints analysis. Furthermore, the progress has been systematically provided as a literature overview, highlighting two aspects: physical constraints and control constraints. Finally, potential prospects of cooperative guidance in addressing the challenges of constraints, providing theoretical support and reference directions for related research.
