In literature problems of this kind are treated by linearization which is not adequate here due to the high nonlinearity of the problem caused by the high gyroscopic torque. This paper addresses the observability and controllability of the rate dynamics for symmetric satellite bodies. Furthermore, robust stability of any bodies is investigated by means of the Krasovskii-LaSalle principle which is a variant of Ljapunov's Second Method. It is found that - apart from one exception - the system is robustly stable for certain conditions depending only on the gain matrix and not depending on the orbit, moments of inertia or initial conditions. The exception is that of the intuitive case of an equator type orbit, in which the satellite rotates around the magnetic field lines, in this case the satellite's rate cannot be damped. Several design configurations are analysed with respect to their performance and cost: Rate damping with magnetometers or gyroscopes as sensors, and torquerods and thrusters as actuators. The results are evaluated with respect to the time to reach the desired rate, the propellant and the power equivalent battery mass used. The goal is to use the results to allow an AOCS equipment and architecture trade-off at an early project phase. The design of the rate damping control of the SWARM project is presented as an example and demonstrated with simulations.}, language = {en} } @article{LazarJarre2016, author = {Lazar, Markus and Jarre, F.}, title = {Calibration by Optimization Without Using Derivatives}, series = {Optimization and Engineering}, volume = {2016}, journal = {Optimization and Engineering}, number = {17/4}, publisher = {Springer}, pages = {833 -- 860}, year = {2016}, abstract = {Applications in engineering frequently require the adjustment of certain parameters. While the mathematical laws that determine these parameters often are well understood, due to time limitations in every day industrial life, it is typically not feasible to derive an explicit computational procedure for adjusting the parameters based on some given measurement data. This paper aims at showing that in such situations, direct optimization offers a very simple approach that can be of great help. More precisely, we present a numerical implementation for the local minimization of a smooth function f:Rn→R subject to upper and lower bounds without relying on the knowledge of the derivative of f. In contrast to other direct optimization approaches the algorithm assumes that the function evaluations are fairly cheap and that the rounding errors associated with the function evaluations are small. As an illustration, this algorithm is applied to approximate the solution of a calibration problem arising from an engineering application. The algorithm uses a Quasi-Newton trust region approach adjusting the trust region radius with a line search. The line search is based on a spline function which minimizes a weighted least squares sum of the jumps in its third derivative. The approximate gradients used in the Quasi-Newton approach are computed by central finite differences. A new randomized basis approach is considered to generate finite difference approximations of the gradient which also allow for a curvature correction of the Hessian in addition to the Quasi-Newton update. These concepts are combined with an active set strategy. The implementation is public domain; numerical experiments indicate that the algorithm is well suitable for the calibration problem of measuring instruments that prompted this research. Further preliminary numerical results suggest that an approximate local minimizer of a smooth non-convex function f depending on n≤300 variables can be computed with a number of iterations that grows moderately with n.}, language = {en} } @inproceedings{VersenKipfelsbergerBernhardt2020, author = {Versen, Martin and Kipfelsberger, Stefan and Bernhardt, Andreas}, title = {Einf{\"u}hrung in die Aufbau- und Verbindungstechnik durch eine interaktive und praxisnahe Qualifizierung in der Leiterplattentechnik}, series = {Tagungsband 2.

Thermoplastic glass fiber composites (organo sheets) play a major role in the production of functional automotive components. Organo sheets are cut, shaped and functionalized by injection molding to produce hybrid components, such as those used in car door modules. The cutting process produces a considerable amount of production waste, which has thus far been thermally recycled. This study develops a closed mechanical recycling process and analyzes the different steps of the process. The offcuts were shredded using two shredding methods and implemented directly in the injection-molding process. Using tensile tests and impact bending tests, the material properties of the recycled materials were compared with the virgin material. In addition, fiber length degradation via the injection-molding process and the influence of the waterjet-cutting process on the mechanical properties are investigated. Recycled offcuts are both comparable to new material in terms of mechanical properties and usability, and are also economically and ecologically advantageous. Recycling polypropylene waste with glass fiber reinforcement in a closed loop is an effective way to reduce industrial waste in a sustainable and economical production process.}, language = {en} } @inproceedings{SeligerDechantKennel2022, author = {Seliger, Norbert and Dechant, Eduard and Kennel, Ralph}, title = {EMI mitigation by substrate integrated common mode filter}, series = {Proceedings of 12th International Conference on Integrated Power Electronics Systems (CIPS 2022)}, booktitle = {Proceedings of 12th International Conference on Integrated Power Electronics Systems (CIPS 2022)}, publisher = {VDE}, address = {Berlin (Germany)}, organization = {Labor f{\"u}r Leistungselektronik und EMV, TH Rosenheim}, year = {2022}, language = {en} } @inproceedings{DechantSeligerKennel2022, author = {Dechant, Eduard and Seliger, Norbert and Kennel, Ralph}, title = {Common Mode DGS EMI Filter Integrated into a GaN Half Bridge Switching Cell}, series = {Procceedings International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM 2022)}, booktitle = {Procceedings International Exhibition and Conference for Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM 2022)}, publisher = {Mesago}, organization = {Labor f{\"u}r Leistungselektronik und EMV, TH Rosenheim}, pages = {6}, year = {2022}, language = {en} } @inproceedings{SeligerFaltlhauser2022, author = {Seliger, Norbert and Faltlhauser, Georg}, title = {Active Expansion Sampling of Magnetic Near-Fields in Unbounded Regions}, series = {Proceedings 26th IEEE Workshop on Signal and Power Integrity (IEEE SPI-2022)}, booktitle = {Proceedings 26th IEEE Workshop on Signal and Power Integrity (IEEE SPI-2022)}, publisher = {IEEE}, organization = {Labor f{\"u}r Leistungselektronik und EMV, TH Rosenheim}, pages = {4}, year = {2022}, language = {en} } @inproceedings{Seliger2023, author = {Seliger, Norbert}, title = {A Differential Relaxation Half-Bridge Oscillator for Inductive Power Transfer}, series = {Proceedings PCIM Europe 2023}, booktitle = {Proceedings PCIM Europe 2023}, publisher = {Mesago GmbH}, address = {N{\"u}rnberg}, pages = {7}, year = {2023}, abstract = {We present inductive power transfer (IPT) with a half-bridge converter based on differential relaxation self-oscillation.

In this study a novel feeding system was developed to enable granulate feeding into gas pressurized processes inside a single- or twin-screw extruder. With this apparatus gas pressure can be applied inside the extrusion process. The apparatus separates the pressurized extruder from the dosing equipment that feeds the extruder. It keeps the pressure inside the system while continuously feeding new material into the process. A small-scale prototype was designed for proof-of concept. The small size of the prototype was able to handle small amounts of granulates of around 100 - 200 g/h. An applied gas pressure of 8 bar was achieved. In future optimizations, throughput can be increased and maximum applied gas pressure towards 15-20 bar.}, language = {en} } @article{ZenzMuscatStruebbe2023, author = {Zenz, Vitus and Muscat, Dirk and Str{\"u}bbe, Nicole}, title = {So wird Bernsteins{\"a}ure aus Holzreststoffen gewonnen}, series = {Plastverarbeiter}, volume = {2023}, journal = {Plastverarbeiter}, number = {04}, publisher = {H{\"u}thig GmbH}, address = {Heidelberg}, pages = {22 -- 25}, year = {2023}, abstract = {Die effiziente Umwandlung von lignocellulosehaltiger Biomasse wie Restholz ist eine wissenschaftliche sowie technologische Herausforderung weltweit.
