This paper presents a design method for an open-loop command preshaping vibrations suppression compensator that ensures a specified dynamic behavior for the original mechatronic system. A reference model is required in the form of a second order custom transfer function. This reference model is build to embed the specified overshot and peak time. Then, a multimodal representation of the original system is created using a parallel composition of independent second order transfer functions for each mode. The compensator calculation is made easy from the two previous models. A numerical example for a 7-DOF merchatronic system is also provided.
