基于SOPC的微型无人机飞行控制系统设计

Design of micro UAV flight control system based on SOPC

针对无人机(UAV)飞控系统的发展要求,提出了一种基于可编程片上系统(SOPC)技术的设计方案,自顶向下地利用软硬件协同设计方法实现整个过程的设计。主控芯片采用Cyclone II系列的EP2C8Q208C8N,进而设计系统的外围电路;借助NIOS II软件写入程序实现对无人机的控制。与传统的无人机控制系统相比,该系统适应了集成度高、功耗低、体积小的发展要求。悬停试飞,机体晃动小,且在外界干扰时能自动调整姿态,保持稳定飞行,具有较快的响应速度。

Aiming at demand for development of unmanned aerial vehicle （UAV） flight control system, propose a design scheme based on SOPC technology. By using method of collaborative design of software and hardware, realize design of whole process from top to down. Use Cyclone II EP2C8Q208C8N as main control chip, and then design peripheral circuit of system. By writing procedures with NIOS II software to achieve control of the UAV. Compared with conventional UAV control system, the system adapts to development requirements of high integration, low power consumption, small size. Its body shakes slightly during hover flight and it can automatically adjust attitude and flight stably with a fast response when there is outside interference.
