Overview of composite anti-disturbance control technology of advanced vehicles

With the rapid development of information technology and artificial intelligence technology, advanced vehicles have been applied more and more widely in military and civilian fields. However, with the increasing complexity of the mission itself and the mission environment, the requirements for flight control are also increasing. Therefore, how to ensure the robustness and safety of flight control systems under the comprehensive influence of external disturbance is one of the research hot spots in recent years. Based on the existing research results at home and abroad, this paper summarizes the research status of composite anti-disturbance technology for advanced vehicles and outlined its future research and development direction. The design principle of the corresponding composite anti-disturbance control is analyzed mainly from the aspects of multi-disturbance observer composite control under multiple time-varying disturbances, composite anti-disturbance control under the combined action of time-varying disturbances and unmodeled dynamics, composite anti-disturbance control under input/output and state constraints, and composite anti-disturbance control based on disturbance coupling utilization. The key technologies that have been solved so far are reviewed. Finally, the future research directions of composite anti-disturbance control technology for advanced vehicles are discussed.
