Abstract

Inthis paper, a quadrotor’s tracking control problem is investigated in which the feedback loop has a time delay caused by transmission. First, the relative motion model is established. Then, an improved Linear Active Disturbance Rejection Controller(LADRC) algorithm is proposed to deal with the time delay in feedback. Finally, simulation and experimental results show the effectiveness of the proposed algorithm.

四旋翼机的改进LADRC算法
研究了反馈回路存在传输时滞的四旋翼飞行器的跟踪控制问题。首先,建立了相对运动模型;然后,提出了一种改进的线性自抗扰控制器(LADRC)算法来处理反馈中的时间延迟。仿真和实验结果表明了该算法的有效性。
