摘要
某型无人机以DSP为核心部件,介绍了其导航/飞控系统硬件设计、结构,其中主要包括数据采集、数据通信,介绍了导航/飞控软件,给出流程框图,设计了用于验证该系统的仿真系统;仿真系统引入大气模拟系统和GPS模拟系统,介绍大气模拟系统结构原理和GPS工作原理,仿真各子系统之间采用CAN总线进行连接,并且挂载真实舵机,检测舵机偏转检测,形成负反馈;最后,给出系统仿真步骤和仿真内容,得出仿真结果,验证该系统可行、正确。
The hardware of certain UAV is based on DSP. The structure of navlgation/flight control system mainly including data acquisition and data communication is introduced. The software of navlgation/fllght control and the flowchart are given as well. A simulation system is designed where the air data system and GPS simulation system are brought in. The principle of the two systems is explained. The sub --systems of the simulation system are connected to each other through CAN bus, real servos are brought into the simulation system and a feedback system is established. At the end, the process and content of the simulation are put up and the results are given which show the navigation and flight control system is feasible and correct.
