Fault Diagnosys in Electromechatronic Systems

Code 11459
Year 1
Semester S1
ECTS Credits 10
Workload OT(15H)
Scientific area Electrotechnics and Electronics
Entry requirements Not applicable.
Mode of delivery The contact time in this curricular unit is of tutorial nature. It is assumed an open participation of students in the discussion of critical issues, even when more theoretical formulations are involved. Questions that arise as a result of student’s study may be presented and discussed at any time. This pro-active participation, when properly accompanied by an individual work of the students, allow them to show a secure knowledge of matters, using correct terminology and acquiring skills for a successful professional life in the future, integrating work teams in the field of fault diagnostics of electromechatronic systems, with special emphasis on research.
Work placements Not aplicable.

Teaching Methodologies and Assessment Criteria In order to allow a fair evaluation of the work developed by each student, the final evaluation will be determined by the following weights:
Seminars: 30%
Computational Simulation Works: 30%
Oral exam: 40%
To obtain approval, the student can not have a mark lower than 20% in the oral exam.
Language Portuguese. Tutorial support is available in English.
