Application of Kalman Filter in the Attitude Four-Axis Aircraft Control System

Attitude control is the core of the four-axis aircraft flight control，By analyzing the principle of four-axis aircraft flight，this paper, on the basis of the traditional method ,acceleration sensors to obtain data, we use the Kalman filter method, fuse acceleration sensor data and gyroscope data, MCU as the core of the inertial measurement unit test，The results showed that，The aircraft can be better stabilized at the test platform, can achieve the requirements of attitude control of the four-axis aircraft.
