Automatic Control


Automatic Control is a compulsory course for the Bachelor course in Mechanical Engineering. It teaches how to solve typical tasks in signal processing and control as well as to handle tasks in the description and analysis of dynamic systems methodically. An emphasis of the course is put on the usability of the methods in practical applications.

The lecture and exercise prints are sold once in the Audimax. After that the new exercise scripts can be purchased from the Mainz publishing house on site or from the publisher's online shop.


Information on RWTHmoodle Course Rooms

Registration for the RWTHmoodle course rooms is usually performed by the students themselves, starting from the lecture site in the RWTHonline system. If you have trouble registering or you need a late registration, please contact your respective advisor.

Lecture content

The detailed lecture contents are as follows:

  • objectives in feedforward and feedback control:
    simple control examples, basic concepts, terms, functional diagram
  • static behaviour
    of control loop elements: plant, measuring devices and actuators; static behaviour
    of control loops: characteristic curves, linearization of nonlinear relations, control factor
  • dynamic behaviour of control loop elements:
    differential equations of dynamic transfer elements, Laplace transformation, transfer, function, frequency response, Nyquist plot, Bode diagram
  • stability of dynamic systems, control loops in particular:
    controller settings, adjustment rules, performance criteria, algebraic and geometric stability criteria
  • linear sampling controls:
    description of discrete time transfer systems, quasi-continuous sampling control
  • Control systems with non-linear transfer elements:
    follow-up controls, switching controllers
  • Multi-loop systems:
    pre-control, feedforward control, auxiliary manipulated and auxiliary controlled variables, cascade control, reference variable filter
  • multivariable control:
    coupling and decoupling of control loops
  • state space:
    introduction to state space control
  • discrete event systems:
    description and analysis of discrete event systems, system modelling with Petri nets

Please note: The lecture reprint is distributed by Verlag Mainz and is available directly from Verlag Mainz in Aachen and in Aachen bookstores. Since a comprehensive revision of the reprint is being worked on for the winter semester 2023/24, the new version of the reprint cannot be purchased early, but only with the beginning of the semester on October 9.


Friday, March 1, 2024, 12 midnight

is the Date of the next exam of automatic control. More informationen can be found in the  RWTHonline.


Consultation Hours and Additional Support

The Institute of Automatic Control offers additional supporting courses. These are offered in winter and summer semester.

These are:

  • Consultation hours:

    Take place on Tuesdays and Thursdays from 11 am to 12 pm in the seminar room of the Institute of Control Engineering.

    Please refer to the Moodle announcements for details on the dates.


No consultation hours

There will be no consultation hours offered between the written examination and the end of the oral examinations. Any exceptions will be announced on the website.
