基于FPGA的无人机控制器设计与实现

摘要

根据无人机系统的控制特点,提出了一种基于FPGA的无人机控制器设计方案,并完成了该方案的软硬件设计.该方案将键盘扫描、AD采样、指令编码与显示和指令异步串行发送等功能模块集成到FPGA内部,简化了控制器硬件结构.实际应用表明,该无人机控制器具有指令群延时低、功能可扩展性强等优点,能够满足使用要求.%According to the control characteristics of the UAV system, the design for UAV controller based on FPGA is proposed in this paper. In order to simplify the hardware structure of the controller, function modules such as Keyboard scanning, AD sampling, instruction encoding and displaying, and UART were integrated into the FPGA. Practical application shows that the UAV controller has low instruction group delay, and able to meet the requirements.
