The input-shaping technique is applied to filtering input signals and the backstepping technique is used to derive the nonlinear controller. Modeling errors are considered as additive disturbances and the con- troller is designed such that the error dynamics is input-to-state stable(ISS). Based on this, a guideline for selecting the controller parameters is given. Finally, simulation results are provided to demonstrate the effectiveness of the proposed controller.
