Development of Virtual Simulation Platform for Automatic Flight Control Based on Unity3D

In order to visualize the relationship between flight control system and aircraft motion state, a virtual simulation platform for automatic flight control is developed based on the creation engine Unity3D. Firstly, a platform design scheme based on numerical calculation and Unity3D is proposed. Then, according to the theoretical teaching content, the mathematical models for typical longitudinal and lateral motion control modes based on state space are established, and the corresponding numerical solution algorithm is designed. At the same time, the interface between numerical solution algorithm and Unity3D, and the human-machine interface is developed according to the requirements of experimental teaching. Finally, the visualization and online virtual simulation of automatic flight control experiment are realized by deploying the designed platform on the school exhibition platform. The application of experimental teaching shows that the designed platform is helpful for students to be familiar with automatic flight control, as well as facilitate the sharing of teaching resources and improve the teaching effect.
