Improving Attitude Estimation and Control of Quadrotor Systems

Estimation and Control of a Tilt-Quadrotor Attitude

The aim of the present work is to continue the development of the prototype ALIV3, focusing on the estimation and control of the attitude. First the differences in motion and configurations of a tilt-quadrotor in relation with a common quadrotor are explained. The mass properties and actuators of the prototype are measured through tests specially developed. In the identification of the motors t...

Quadrotor Accelerometer and Gyroscope Sensor Fault Diagnosis with Experimental Results

This paper presents the design and real-time experimental results of a fault diagnosis scheme for inertial measurement unit (IMU) measurements of quadrotor unmanned air vehicles (UAVs). The objective is to detect, isolate, and estimate sensor bias fault in accelerometer and gyroscope measurements. Based on the quadrotor dynamics and sensor models under consideration, the effects of sensor fault...

Design of Attitude Control System for Quadrotor

Quadrotor is a widely used aircraft now and be with the nonlinear, uncertain characteristics. Because of requirement on high attitude stability the attitude control system of quadrotor needs to be well designed. Firstly the movement pattern and working principle of the quadrotor are analyzed. Then the hardware schematic diagram of attitude control system is designed which includes several senso...
