The module examination will take place in written form at the end of the module. The examination lasts 60 minutes. The students have to answer multiple-choice-questions (20% max) in order to examine their understanding of the theory of reliability considerations, as well as the relevant technical terms. The transfer of this theory, the knowledge of the different models, the understanding considering system requirements, and the ability to calculate the corresponding values will be examined by arithmetic exercises.
Fundamentals on electric drives (electrical machines and power electronics)
The following modules are recommended to pass before participation: - Electrical Machines [EI8028] or Elektrische Maschinen [EI7326]
Fundamentals on safety-critical systems, their requirements and the significance considering reliability of electric drives. The following topics are mainly covered: - technical terms of reliability assessment - methods of reliability evaluation - reliability of the drive's components - demarcation reliable vs. fault-tolerant systems - monitoring, diagnostics, and fault detection - risk analysis and management of electric drive in operation
After successful completion of the module, students understand the theory of reliability considerations and are able to combine this with the analysis of electrical drives. The students understand the requirements of safety-critical systems. Furthermore, students can name the relevant technical terms, differentiate them from each other and calculate the corresponding values. The students know different models and their function in order to be able to analyze systems regarding their reliabili
In addition to the students' own learning methods, detailed knowledge transfer takes place through exercises in which thematic problems are discussed and in some cases solved independently. During lectures and exercises, mainly frontal teaching is used as a teaching method. During the exercises, problems and tasks are also provided (discussions, evaluations and analyses of simulation results, solution approaches, ...).
The following media are used: - presentation slides - manuscript - exercises with solutions - all materials are available on Moodle
