| 英文摘要 |
| Aiming at the problem of clearing tree obstacle near power transmission lines, this paper proposes a new
hanging telescopic cutter for tree obstacle clearing aerial robot contact and carries out simulation and physical verification.
Firstly, the dynamics, kinematics and contact modeling of the aerial robot with telescopic tool hanging are carried out
under the change of the tool center of gravity. Force estimator and admittance controller are designed for force sensing and
force control in order to avoid the problem of robot tipping during contact operation. A linear active disturbance rejection
(LADRC) robot pose controller is designed to solve the problems of nonlinear strong coupling, parameter perturbation
and operation disturbance of aerial robots. The simulation results show that the admittance control can effectively avoid
the tipping problem of aerial robots during contact operation, and the LADRC controller based pose control has good
stability and disturbance resistance. Finally, physical flight and contact operation tests further verify the effectiveness of
the proposed aerial robot and its control method. |
