The Design of Flight Control System for Mini UAV

Xianlin Mei, Yunfeng Cao

Abstract


The structure of a flight control system for mini unmanned aerial vehicles is presented which is based on the ARM microprocessor and embedded operating system. The information of mini UAV such as attitude, position, heading, altitude and so on are provided by the low cost Microelectromechanical Systems (MEMS) including accelerometer, gyro, Global Position system receiver, magnetometer and static-pressure measurement system. As the output of MEMS sensor drifts by time and temperature, so some compensation is needed to give a reliable estimate of attitude using a new complementary filter constructed by accelerometer, rate gyro, and magnetometer. Flight control system makes the realization of autonomous fly for Mini unmanned aerial vehicles. The result of simulation indicates that the fly control system has good performance and can keep the stabilization of mini unmanned aerial vehicle when disturbance is added to the system.
