@misc{8384, abstract = {{ynamic simulation models are widely utilized to evaluate complex technical components and systems like electric drives or machines. They can support the development process of a production machine by avoiding an inadequate layout of components or an erroneous control design. However, the effort for building them is often too high for this purpose (lot size one). An automated model generation can be utilized to overcome the gap between efforts and advantages of dynamic simulations. This contribution presents an approach for simplifying the dynamic model generation of production machines by using the so-called Asset Administration Shell defined by the initiative Platform Industrie 4.0. The Asset Administration Shell was developed to aggregate all data necessary for maintaining the product across its life cycle. This includes component data and models as well as structural information about a machine. The generation process is performed by using the common FMI standard and a two-step procedure which allows the linkage of different simulation tools. The model generation is demonstrated by an example layout of a machine's internal direct current grid.}}, author = {{Göllner, D. and Pawlik, Thomas and Schulte, Thomas}}, booktitle = {{2021 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM)}}, isbn = {{978-1-6654-3772-1 }}, issn = {{2157-3611}}, keywords = {{Digital Twin, Asset Administration Shell, Dynamic Simulation Model, Industry 4.0, Automated Model Generation}}, location = {{Online (Singapore)}}, pages = {{808--812}}, publisher = {{IEEE}}, title = {{{Utilization of the Asset Administration Shell for the Generation of Dynamic Simulation Models}}}, doi = {{10.1109/IEEM50564.2021.9673089}}, year = {{2021}}, } @misc{8385, abstract = {{Currently, numerous single-track railway lines are disused due to economic reasons. However, they could be reactivated for a bidirectional on-demand service traffic by small vehicles that use only one rail. MonoCabs are such small cabin-like vehicles, stabilized by a system of control moment gyroscopes and a moveable mass. They could make an important contribution to improve the mobility offer especially in rural areas. This paper focuses on the analytical modeling and vertical stabilization system of the MonoCab. A nonlinear dynamic model is obtained using the Lagrangian method and subsequently linearized about its equilibrium point. Which is used for the design of the cascade control system. The dynamic analysis of the system is accomplished by comparing between analytically derived model in simulink environment and same structured model in simscape multibody. This system is discussed based on a physical three body model which describes the rolling motion of the vehicle, the lateral motion of the mass and the precession motion of the gyroscope. The model is utilized for a cascaded control concept adjusting the vehicle’s roll angle and gyroscope’s precession angle. The proposed stabilization concept is capable of compensating both high dynamic disturbances and stationary disturbances (e. g. unbalanced loads and steady wind flows). The concept is analyzed by simulations and experimental investigations. Beside transient command responses also the frequency response of the system is experimentally evaluated and used for a validation of the model and theoretical findings. For the experimental validation, a small scaled test rig is used which consists of mechanical frames and flywheels, inverter-fed drives, rotary encoders, an inertial measurement unit (IMU) and a rapid control prototyping system.}}, author = {{Griese, Martin and Mousavi, Seyed Davood and Schulte, Thomas}}, booktitle = {{2021 9th International Conference on Control, Mechatronics and Automation (ICCMA)}}, keywords = {{Vehicle dynamics, Control moment gyroscope, Control system analysis, Roll stabilization, Monorail vehicles}}, location = {{Belval, Luxembourg }}, pages = {{205--210}}, publisher = {{IEEE}}, title = {{{Modeling the Vertical Dynamics of a Self-stabilizing Monorail Vehicle}}}, doi = {{10.1109/ICCMA54375.2021.9646219}}, year = {{2021}}, } @misc{8386, abstract = {{The dynamic emulation of mechanical loads is required in a variety of applications to test and validate control algorithms. Typical test setups consist of two mechanically coupled motors, one of which is the Device Under Test (DUT) while the other is used as a load drive for emulation. Existing emulation concepts either rely on the differentiation of velocity feedback or utilize measured quantities of the DUT. The emulation method proposed in this paper uses acceleration feedback to control the torque of the load drive. It does not require any measured quantities of the DUT which allows a simple replacement of the DUT’s motor and/or inverter without the need of any conceptual changes. Based on a physical model, the emulation method is derived analytically and analyzed numerically for the emulation of one-mass-systems. The stability and emulation quality is evaluated considering two controller architectures.
