【摘要】 针对小型空中机器人导航/飞控系统硬件设计难这一实际情况,设计了一种新的基于DSP和CPLD的空中机器人导航/飞控系统,该系统具有结构紧凑、多串口通信可靠、接口灵活等特点。提出了一种新的基于CPLD的遥控/飞控切换电路的设计方法,并着重说明了双口RAM在该系统中的应用。通过半物理闭环仿真实验证明该系统功能完善、性能可靠。更多还原

【Abstract】 The present Navigation/Flight control system design method of UAV can’t be used in small or micro UAV. In this paper, a new navigation/flight control system design of a UAV based on DSP and CPLD is presented. The structure is compact, multi serial communication is credible, and the interface is flexible. A new circuit design which makes change between telecontrol and flight control is offered. The application of Dual-Port Static RAM is especially illuminated. The result of looped-simulation experimentation is given which shows the Navigation/Flight control system is multifunctional and reliable.更多还原
