Application of Operator Inference to Reduced‐Order Modeling of Constrained Mechanical Systems
ABSTRACT Constrained mechanical systems occur in many applications, such as modeling of robots and other multibody systems. In this case, the motion is governed by a system of differential–algebraic equations (DAE), often with large and sparse system matrices.

Learning Differential Equations From Numerically Integrated Artificial Neural Networks
ABSTRACT For numerical investigation of dynamical systems, the formulation of the corresponding ordinary differential equations (ODE) based on physical principles is usually the first and most crucial step. However, if the underlying physics is not fully understood or the required expert knowledge for modeling is missing, setting up these differential ...

Global Chassis Control: Integration Synergy of Brake and Suspension Control for Active Safety [PDF]
The paper deals with the investigation of integration synergy of brake and suspension control for reduction of the stopping distance. The basic idea is to take a controllable suspension and to optimize it for decrease of road-tyre force fluctuation.

Optimal control of a biomechanical multibody model for the dynamic simulation of working tasks
S.817-826In this contribution a framework for digital human modelling using optimal control of a biomechanical multibody model is presented. The skeleton of the human body is represented as a multibody system, actuated by simplified Hill muscles. Motions

Control and optimization of semi-passively actuated multibody systems
The controlled multibody systems are under consideration. Several questions are addressed about the role of inherent dynamics, and how much multibody system should be governed by external powered drives and how much by the systems inherent dynamics ...

Multibody Dynamics Model of a Human Hand for Haptics Interaction [PDF]
In this paper we propose a strategy for modelling a human hand for Haptics interaction. The strategy consists in a parallel computing architecture that calculates the dynamics of a hand; this is accomplished by computing the dynamics of each finger in a ...
