| With the development of science and technology, aircraft equipment desires muchhigher level flight control system which is one of the core technologies of aircraftcontrol. In order to meet the real-time and reliability requirements of modern aircraft,this dissertation presents the design of a flight control simulation system based onVxWorks.Firstly, this dissertation will introduce the development platform of this project,including how to build and how to use VxWorks operating system and the TornadoIntegrated Development Environment. Then, it will analyze of the basic structure of theVxWorks BSP (Board Support Package), add multi-serial device drivers and networkdevice driver based on the BSP template provided by Beijing Bochuang Corporationand establish serial communication and Ethernet port communication. Then, thisdissertation will analyze the I\O system call methods of VxWorks and design a flightsimulation using stepper motor as the aircraft tail. This project designs a flexible andeffective aircraft flight control simulation system with practical background andfacilitates observation. In addition, this project provides better user visual experienceusing animated simulation based on the OpenGL3D graphics interface and MFCinterface support. Finally, the prototype system and the animated simulation system areconnected using the network communication, real-time data collected by the dataacquisition module will control the animated simulation system, and data acquisitionsystem will upload data to the prototype system through serial communication.To sum up, this project designs a aircraft control simulation system and verifiesthat this system which is based on VxWorks operating system is qualified for real-timeand reliable use. This project also establishes a stable practical and theoretical basis forlatecomers of the aircraft control study. |
