... independently. In addition, this method provides an effective estimation on the bound of the motion of the helicopter. Therefore, even in the case where the helicopter motion is unknown, the cable robot can be stabilized by implementing a robust controller. Simulation results of the dual system show...

.... In this paper, we look at a planar version of this two-stage cable robot. The disturbance motion from the sea is considered while modeling the dynamics of robot. The problem of robust control of the end-effector in the presence of unknown disturbances, along with maintaining positive tensions in the cables...

... actuators robust control controllers In recent years considerable attention has been paid to the development of theories associated with artificial neural networks (ANN). The need to meet the demanding control requirements in increasingly complex dynamic systems under significant uncertainties makes...
