These so called self-optimizing systems adapt their objectives and behavior autonomously and flexibly to changing operating conditions. On the one hand, securing the dependability of such systems is challenging due to their complexity and non-deterministic behavior. On the other hand, self-optimization can be used to increase the dependability of the system during its operation. However, it has to be ensured, that the self-optimization works dependable itself. To cope with these challenges, the multi-level dependability concept was developed. It enables predictive condition monitoring, influences the objectives of the system and determines suitable means to improve the system's dependability during its operation. In this contribution we introduce a procedure for the conceptual design of an advanced condition monitoring based on the system's principle solution. The principle solution describes the principal operation mode of the system and its desired behavior. It is modeled using the specification technique for the domain-spanning description of the principle solution of a self-optimizing system and consists of a coherent system of eight partial models (e.g. requirements, active structure, system of objectives, behavior, etc.). The partial models are analyzed separately in order to derive the components of the multi-level dependability concept. In particular, the reliability analysis of the partial model active structure is performed to identify the system elements to be monitored and parameters to be measured. The principle solution is extended accordingly: e.g. with system elements required for the realization of the dependability concept. The advantages of the method are shown on the self-optimizing guidance module of a railroad vehicle."}],"title":"Conceptual Design of Advanced Condition Monitoring for a Self-Optimizing System based on its Principle Solution","user_id":"55222","author":[{"full_name":"Sondermann-Wölke , Christoph","first_name":"Christoph","last_name":"Sondermann-Wölke "},{"full_name":"Meyer, Tobias","first_name":"Tobias","last_name":"Meyer"},{"last_name":"Dorociak","first_name":"Rafal","full_name":"Dorociak, Rafal"},{"first_name":"Jürgen","full_name":"Gausemeier, Jürgen","last_name":"Gausemeier"},{"full_name":"Sextro, Walter","first_name":"Walter","id":"21220","last_name":"Sextro"}],"quality_controlled":"1","publication":"Proceedings of the 11th International Probabilistic Safety Assessment and Management Conference (PSAM11) and The Annual European Safety and Reliability Conference (ESREL2012)","department":[{"_id":"151"}],"keyword":["Mechatronic Systems","Principle Solution","Condition Monitoring","Conceptual Design"],"status":"public","date_created":"2019-05-13T13:41:34Z"},{"author":[{"last_name":"Hunstig","first_name":"Matthias","full_name":"Hunstig, Matthias"},{"first_name":"Tobias","full_name":"Hemsel, Tobias","last_name":"Hemsel","id":"210"},{"first_name":"Walter","full_name":"Sextro, Walter","last_name":"Sextro","id":"21220"}],"quality_controlled":"1","keyword":["Piezoelectric Inertia Motors","Drive Signals","Stick-slip","Slip-slip"],"department":[{"_id":"151"}],"publication":"ACTUATOR 2012 Conference Proceedings","status":"public","date_created":"2019-05-13T14:11:37Z","abstract":[{"lang":"eng","text":"Piezoelectric inertia motors, also known as ``stick-slip-drives'', use the inertia of a body to drive it by means of a friction contact in small steps.

In this contribution, a one degree of freedom model of an inertia motor driven by an ideal actuator is analysed. Start-up and constant velocity operation of the motor are investigated and appropriate quantities to compare ``stick-slip'' and ``slip-slip'' operation are determined. Different aspects such as velocity, uniformity of motion, load capacity, robustness, efficiency, and wear are considered. The analysis allows both modes to be applied advantageously in different applications and can widen the field of application of piezoelectric inertia motors.

To\r\nthis end, the reflectivity of glass surfaces with topographies represented by linear, parabolic and Fermishaped\r\nglass/air fill factor profiles is calculated for normal incidence. It is shown that using the latter ones,\r\nan almost complete suppression of reflections can be achieved.

The crystal volume grows roughly linearly from LT to LN, whereby the lattice parameters a and c show minor deviations from the Vegard behavior between the end compounds, LiNbO3 and LiTaO3. Our calculations in the framework of the density functional theory show the TO1, TO2 and TO4-modes to become harder with increasing Nb concentration. TO3 becomes softer with increasing Nb content, instead. The frequency shifts of the zone center A1-TO phonon modes for crystals with different compositions are found to be as large as 30 cm-1. Raman spectroscopy, which is sensitive to the A1 modes, can be therefore employed to determine the crystal composition.","lang":"eng"}],"date_created":"2018-09-12T14:32:09Z","status":"public","department":[{"_id":"15"},{"_id":"230"},{"_id":"35"}],"keyword":["Ferroelectrics","Vibrational properties","LiNbO3","LiTaO3","Mixed Crystals"],"publication":"Proceedings of ISAF-ECAPD-PFM 2012","author":[{"first_name":"Simone","full_name":"Sanna, Simone","last_name":"Sanna"},{"last_name":"Riefer","first_name":"Arthur","full_name":"Riefer, Arthur"},{"first_name":"Sergej","full_name":"Neufeld, Sergej","last_name":"Neufeld"},{"full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero","last_name":"Schmidt"},{"last_name":"Berth","id":"53","first_name":"Gerhard","full_name":"Berth, Gerhard"},{"first_name":"Alex","full_name":"Widhalm, Alex","last_name":"Widhalm"},{"id":"606","last_name":"Zrenner","full_name":"Zrenner, Artur","orcid":"0000-0002-5190-0944","first_name":"Artur"}]}]
