Attitude Control of Quadrotor UAV Based on LADRC Method
2019 Chinese Control And Decision Conference (CCDC), 2019Quadrotor Unmanned Aerial Vehicle (UAV) contains nonlinearity and strong coupling, and it is susceptible to external disturbance. Herein, a design method of attitude control of UAV is presented based on Linear Active Disturbance Rejection Control (LADRC) theory. A transition process is firstly arranged to decrease the overshoot and improve the rapidity
