Design of Mechatronical Systems, 7.5 credits

Main field of study with advanced study

The courses Design and Visualization 7.5 credits, Machine Elements 7.5 credits, Programming 7.5 credits, Control Systems 7.5 credits, Sensors, Signals and Systems 7.5 credits and 30 credits mathematics. English 6. Exemption of the requirement in Swedish is granted.

The course is a part of Master of Engineering in Mechanical Engineering, Sustainable Design and Innovation.

The course aims for students to develop advanced knowledge in the subfields of mechatronics, including control systems, sensor systems, computer systems, and actuators. Furthermore, the course aims for the student to develop skills and abilities in using computer-aided design for product development, as well as how to realize a product through the design and selection of components, software design, mechanics, and realization of mechanical parts through additive manufacturing.

Following successful completion of the course the student should be able to:

Knowledge and understanding

• explain how basic mechatronic control systems are organized
• describe the challenges that exist in the design of mechatronic computer systems where software and hardware are designed in interaction
• discuss how the uncertainty in a measurement value is calculated and presented

Skills and ability

• deal with concrete problems in the design of mechatronic systems and translate these into mathematical models with appropriate idealizations
• use computer-aided tools for product optimization
• use additive manufacturing for the realization of mechanical parts

Judgement and approach

• evaluate and analyze different technical solutions and present these in writing and orally
• evaluate the validity of the models produced and critically analyze their results in relation to the requirements

The course starts with lectures on how mechatronic products are often a complex, optimized combination of electromechanical solutions and embedded systems. Successful development of such products requires good knowledge of the different components and how they affect each other.

The course is structured around laboratory sessions with associated lectures and exercises dealing with a mechatronic system's central parts.

The following elements are included:

• Modelling and simulation, and programming of the embedded system. An understanding of the final system can be obtained through simulation and modelling. In this process, computer-aided product development is essential for realizing a product.
• Actuators: Electric motors, gearboxes. Control: Cascade control and velocity profile.
• Sensors: Gyro, accelerometers and position estimation.
• Mechanics: Design and construction of mechanical components. Stress analysis. Printing of mechanical parts with 3D printers.

The course ends with a project where a mechatronic system is developed and evaluated against set requirements and simulations. The project is carried out in groups and is presented orally and in writing in a technical report.

The teaching includes lectures, exercises and laboratory work. Part of the course is studied in project form.

Examinations occur through laboratory work in groups and project work in groups, with written and oral presentations. Participation in laboratory sessions is compulsory.

If there are special reasons, the examiner may make exceptions from the specified examination format and allow a student to be examined in another way. Special reasons can e.g. be study support for students with disabilities.

Course evaluation is part of the course. This evaluation offers guidance in the future development and planning of the course. Course evaluation is documented and made available to the students.
