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 EP2C8Q208C8 N 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.
