Stable Inversion for Flexible Multibody Systems Using the ANCF [PDF]
PAMM, 2021 AbstractFlexible robots are often non‐minimum phase systems. Thus, their inverse model must be computed by stable inversion. Here, a simplification to the stable inversion process is proposed, which enables its application to complex underactuated multibody systems.

Linear dynamics of flexible multibody systems [PDF]
Multibody System Dynamics, 2016 A new methodology to derive the linear model of flexible multibody system dynamics is presented in this paper. This approach is based on the twoport model of each body allowing the model of the whole system to be built just connecting the inputs/outputs of each body model.

Improved Craig–Bampton Method Implemented into Durability Analysis of Flexible Multibody Systems
Actuators, 2023 The Craig–Bampton method is frequently applied in most commercial multibody dynamic software. Nevertheless, the Craig–Bampton modes only represent the free-free modes in flexible multibody systems.
