Here article describes in detail the design and the process of making the four-rotor aircraft, including Quad- rotor UAV aircraft flight principle, hardware introduction and selection, implementation and realization of derivation attitude reference algorithm, the system software . The Quad- rotor aircraft control system STM32f103zet microcontroller core, and the advantages and disadvantages based on the accelerometer sensor, a gyro sensor and pass sensors using different correction methods for correcting various sensor data and low-pass digital filter processing, after plementary filter to estimate the optimal posture, precise attitude measurement. Finally, GPS control and attitude control PID control is superimposed four-rotor aircraft four motors to achieve a variety of flight maneuvers to achieve the purpose. Four-rotor aircraft in the production process, a lotof debugging and parison with the existing excellent algorithm validation, the final design to stabilize the Quad- rotor UAV flying aircraft.
