Research on Behavior Modeling and Simulation of Complex UAV Based on SysML State Machine Diagram

Modeling and simulation of Unmanned Aerial Vehicle (UAV) behavior is a key issue in dealing with complexity. In this paper, a behavior modeling and simulation method based on System Modeling Language (SysML) state machine diagram is proposed for the complex UAV system. The methodology includes: state definition, black box modeling, white box modeling, simulation verification criterion and test case generation. Taking UAV landing gear management behavior as an example, the application and practice of the above modeling and simulation methods are carried out. The results show that this method can effectively express and verify the functional requirements of the UAV and the correctness of the operation logic.
