Course content

The course will introduce students with the principles of predictive maintenance facilitated by digital twins. Central to the concept of digital twins is the optimization of physical sensor usage on real assets. The fundamental idea involves constructing a simulation model, utilizing analytical, finite element, or big data models, to replicate the behavior of the physical asset. This digital twin is then equipped with virtual sensors that furnish supplementary information crucial for predictive maintenance and decision support. Implementation of the digital twin can take the form of a swift local edge, a gradual IoT cloud solution, or a combination of both for optimal flexibility. This approach not only minimizes reliance on physical sensors but also enhances adaptability in deploying digital twins tailored to specific operational needs. The course contains a selection of the following topics:

• Modelling and simulation
• State and parameter estimations/filters
• Actuator and sensor systems
• Condition monitoring and predictive maintenance
• Inverse methods
• Edge and cloud solutions

More details about the curriculum will provided during the start of semester.

• The student can formulate scientific problems, propose solutions, and present results both orally and in writing to a technical audience
• The student can make evaluations about societal and ethical aspects of technological developments

Learning methods and activities

Learning activities generally include a mix of lectures, tutorials and practical lab/project work. A constructivist approach for learning is endorsed, with focus on problem solving and practical application of theory.

Compulsory assignments

• Compulsory learning activities

Further on evaluation

The final grade is based on an overall evaluation of the portfolio, which consists of work that is carried out, documented and digitally submitted during the term. The assignments may consist of the following:

• video demonstration of the work
• class presentation
• technical report
• possibly other kinds of assignments.

Both individual and team assignments may be given. Assignments are designed to help students achieve specific course learning outcomes, and formative feedback is given during the period of the portfolio.

The re-sit exam is an oral exam in August.

Note that the course also has some compulsory activities that must be approved in order for the portfolio to be assessed.

More information will be provided at the start of the course.
