Aim

The course aims to provide basic knowledge of electric and control technology, and to give understanding and knowledge of the function and design of electrical and control components, equipment and systems that are part of modern industrial and energy facilities. This knowledge improves cooperation between mechanical engineers and other engineers in solving common electrical and control engineering technical problems.

Learning outcomes (after completion of the course the student should be able to)

  • calculate voltage, current and electric power in simple DC and AC systems.
  • describe the function and design of common electrical components, equipment and systems included in modern industrial and energy facilities.
  • apply electrical concepts needed in the cooperation between mechanical engineers and electrical engineers in solving common electrical problems.
The students should also be able to:
  • give examples of a number of control engineering applications, especially mechanical engineering applications in vehicles, cars, robots, and factories.
  • explain how the feedback principle works and give several examples of it.
  • explain the principle of a PID controller and how the three components (P, I and D) impact the control properties.
  • set up mathematical models of simple processes and to solve simple control problems using transfer functions, Laplace transforms, block diagram transformation and frequency functions.
  • simulate simple control system with Matlab / Simulink and to use simple design methods for PID controllers.
  • describe typical components of feedback and control engineering systems, for example sensors, relays and actuators.
  • describe how to build simple control systems with relays.
