Research On Flight Control System Architecture Of Ship-borne UAV Based On MBSE

With the complexity of flight control system is getting higher and higher,the traditional document-based development method has been difficult to meet the needs of system development.Along with the development of MBSE,the development of complex systems has slowly shifted to model-based approaches.In this paper,the ship-borne UAV flight control system as a research object,the use of MBSE development method,the flight control system with automatic landing function,for the entire UAV flight control system architecture modeling research.Firstly,the three pillars of model-based system engineering practice are studied.This paper makes a deep research on some modeling languages,modeling methods and modeling tools,and compares them with each other,summarizes their advantages and disadvantages,and then determines the best practice for the study of flight control system architecture.Combination by SysML,Harmony-SE and Rational Rhapsody.Secondly,the requirements engineering and function of flight control system are analyzed.And analyzed the ship-borne UAV requirements before deeply studying the process of UAV on the ship.The functional requirements and nonfunctional requirements of the system are refined and introduced into Rational Rhapsody,and the corresponding system use case model is established to analyze the main functions of the system.Thirdly,the architecture of the flight control system is studied.At the same time,the architecture of the ship-borne UAV is analyzed and designed.Aiming at the several key functions of UAV automatic control system,the trade-off analysis of its candidate scheme is carried out.After determining the final solution of the system,the flight control system architecture is modeled in the Rhapsody environment.Finally,after determining the main contents of the flight control system verification,a system architecture verification platform based on state behavior is built in Rhapsody environment.The state of the UAV process is modeled using the state diagram and the sequence diagram respectively.The correctness of the model is verified by the model 0 error and the 0 warning.
