英文摘要 |
In this paper, aiming at the problem of backlash force interference and attitude control when using quadrotor
unmanned aerial vehicles (UAV) to clean insulators, a method of anti backlash force control for cleaning insulator of
quadrotor UAV is proposed. For the UAV system, this paper uses the backstepping method in the nonlinear control methods
to design the attitude controller to make the system stable in input to state and robust to external disturbance. In this paper,
the dynamic equations of the quadrotor UAV attitude system is first established. Then, the Bernoulli equation in fluid
mechanics and momentum theorem are used to model the backlash force. After that, an attitude controller is designed
by backstepping method and its stability is proved. Finally, simulation experiments of UAV systems are performed by
MATLAB. The results prove the effectiveness and robustness of the proposed control method. The control method proposed
in this paper can avoid the shortcomings of some existing technologies and provide development space for anti disturbance
control of UAV and insulator cleaning. |
