Real-time pose estimation and motion control for a quadrotor UAV

, 2014
Real-time pose estimation and reliable motion control are two crucial tasks for a quadrotor UAV. In order to obtain accurate and robust pose estimation, an estimation algorithm based on Cubature Kalman Filter (CKF) is adopted in this paper.

Model reference quasi-LPV control of a quadrotor UAV [PDF]

, 2014
In this paper, a solution for the attitude/altitude tracking control problem is proposed for a quadrotor Un-manned Aerial Vehicle (UAV). The solution relies on the use of a reference model, where the resulting nonlinear error model is brought to a quasi-

A Mixed H2/H∞ Control Method for UAV Based on T-S Fuzzy Model

Kongzhi Yu Xinxi Jishu, 2018
A mixed H2/H∞ control strategy was proposed in this paper to achieve a stable tracking trajectory of the UAV(unmanned aerial vehicle). Firstly, the quadrotor UAV was divided into three subsystems: the altitude, the position and the attitude. By selecting
