Abstract:
Aiming at the contact operation problem of aerial manipulator， a non-singular terminal sliding mode compliant control algorithm for aerial manipulator based on disturbance observer is designed. The algorithm introduces disturbance observer on the basis of nonsingular terminal sliding mode control. The disturbance is estimated to reduce the system estimation error， the disturbance of the manipulator and the influence of external disturbance on the rotorcraft. Finally， the simulation results show that the proposed controller has good robustness. Meanwhile， it can reduce the system estimation error， the disturbance of the manipulator and the external disturbance， and ensure the stability of the contact force under smooth movement.
