Abstract:
A sliding mode-neural network scheme based on hybrid trajectory was proposed to track the hybrid trajectory of a space flexible manipulator, meanwhile, the flexible vibration can be suppressed. In order to actively suppress the flexible vibration, the hybrid trajectory for sliding mode-neural network controller was generated by using the virtual control force concept, which reflected the flexible variables as well as the rigid desired trajectories. Based on the hybrid trajectory, the new sliding mode-neural network control can be designed. Simulations results confirm that the proposed control scheme can dominates the trajectory tracking the coordinated motion and actively suppress the vibrations in the presence of parameter uncertainty.
