摘要
Abstract
Aiming at the nonlinear and strong coupling characteristics of quadrotor aircraft,as well as the attitude control problems with modeling errors and unknown disturbances,an improved active disturb-ance rejection control scheme is proposed.The feedback linearization method is used to convert the attitude dynamics model of unmanned aerial vehicles into a linear model,reducing the system error caused by small disturbance assumptions;the structure of the extended state observer(ESO)is improved so that it can simultaneously use the measurement information of angle and angular velocity to improve its estimation accuracy for time-varying disturbances;based on the improved ESO,the design of an active disturbance rejection controller was completed and the stability of the control system was demonstrated.The simula-tion experimental results show that the self-disturbance rejection controller based on improved ESO has strong anti-jamming and robustness.关键词
