A Design For Hardware Of Automatic Flight Control System

With unmanned air vehicle (UAV) play an important role, more and more in the field of military and civilian, UAV research also be more and more attached attention around the world in general. As the core of a UAV control, Automatic flight control system is the focus of the UAV study.This paper designed and actualized a UAV flight controller base on ARM on the basis of analysis of the UAV flight control theory and system component. Acquisition of the necessary flight parameters of the sensor modules was selected. It is based upon the requirement of sensor and systemic task. Completed the AD signal acquisition, UART and SPI serial interface design, tested the sensor modules. Designed conversion control between remote control and autonomous flight mode and improve flight safety; Expansion of the data storage circuit to meet the requirements of record flight parameters, accomplished overall design of hardware of the flight control system and completed a printed circuit board production. Subsequently, developed driver and initialization of ARM bottom interface under ADS environment. Control system was connected and experimented for the basic functions of running of data acquisition and steering gear control. Experimental results show that the system can achieve the real-time data collection of the sensor modules and can control the steering gear at any point quickly; so it has laid a foundation of hardware for further study of UAV flight control.
