This paper describes the wave control of suspended rope by using the control law based on a finite difference (FD) model. The non-existing term in the boundary node equation due to the boundary condition is restored by control, which is computed with the wave propagating solution of the interior node equation as if no boundary existed. The wave propagating solution of the finite difference suspended rope system is newly derived in this paper by introducing the new variable of the difference between adjacent displacements. A similar process to the multiple pendulums system study (2) is applied to the finite difference rope system and the displacement transfer function between adjacent node displacement in frequency domain and the convolution integral kernel function in time domain have been obtained. The frequency analysis and numerical time simulation have confirmed the wave control characteristics of the control law. The simulation of the suspended rope system with load at the bottom has also been conducted and shown the controllability superior to wave control of the non-homogeneous multiple simple pendulum system
