MIE012, 9 credits, G2 (First Cycle)

Valid for: 2016/17
Decided by: Education Board A
Date of Decision: 2016-04-05

General Information

Main field: Technology.
Compulsory for: M3, MD3
Language of instruction: The course will be given in Swedish

Aim

Mechanical engineers need to use more electronics today than ever before. Most products, processes, and systems involve one or more of the following items:

 

• measurement of electrical and non-electrical variables;
• signal processing;
• analogue and digital, power electronic and electromechanical energy conversion.

To be able to structure and use such technology, the engineer needs basic knowledge of electronics. The aim of this course is to give a broad knowledge of the wide field from Ohm’s law to computer-based control of servo motors.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to account for the theory of DC and AC circuits
• have basic knowledge in applied electronics, both analogue and digital
• have basic knowledge in electric measurement, sensors and how signals are amplified and filtered
• have basic knowledge in how electric machines in industrial drive systems work and are controlled
• have basic knowledge in Boolean algebra, digital combinatorial networks, the structure of the micro computer and basics for its programming
• have basic knowledge in programming of a PLC-system (industrial programmable digital control systems).

Competences and skills
For a passing grade the student must

• be able to analyse basic DC and AC circuits
• be able to suggest and analyse basic circuits in signal electronics, e.g. suggest a circuit for interfacing a sensor signal to its control computer
• be able to elect a suitable industrial drive system for a given application
• be able to perform basic automation control using a PLC-system.
