In recent years

quadrotor is widely used in the field of military and civilian because of its simple mechanical structure and its relative complex attitude control. In order to realize stable control of aircraft attitude

by setting up flight control platform of quadrotor. Firstly discuss flight principle and mechanical structure of quadrotors

then overall structure of hardware system is given. On the basis of integration of each function modules

realize hardware circuit design of flight control system based on multi-sensors. Simulation and experimental results show that in using process of multi-sensors

data integration by Kalman filtering effectively solves problem that accelerometer and gyroscopes are susceptible to be interfered by outside

the designed hardware system has stable performance in flying experiment

provide reference for stable control of quadrotor.
