摘要
设计了一种以FPGA和DSP为硬件核心的模型直升机飞行控制系统,以飞控计算机为研究重点,介绍了其硬件结构和软件设计。为验证飞控系统功能上的可靠性,编写了相应的软件,完成了基于数控转台的地面测试实验。在数控转台和地面站两种环境下分别实时测量三轴姿态角,对所得数据的分析表明设计的飞控系统工作正常,数据通路正确,为模型直升机飞控的开发奠定基础。
A model helicopter flight control system with FPGA and DSP as its hardware core is devised with the flight control computer as the research focus, and corresponding hardware structure and software are intro- duced. To verify the functional reliability of the designed flight control system, corresponding software is writ- ten, and a ground test experiment based on the NC turntable is completed. The 3-axis attitude angles are meas- ured in real time under the environment of NC turntable and ground station respectively, and the analysis on the obtained data shows that the designed flight control system works well with correct data path, which has laid a solid foundation for the development of model helicopter flight control.
