Digital Control Systems

Instructor and contact person:

Dr.-Ing. Karl-Peter Jäker

Content and learning objectives:

Functioning of digital control

  • standard control-loop system, hardware-in-the-loop techniques

Synthesis of digital controllers

  • Design in discrete and continuous systems
  • Modelling of digital controls

Implementation on digital computers

  • Discretization, simulation methods, code generation
  • Aliasing

Mathematical methods

  • z-transformation, sample-and-hold element
  • frequency response of discrete systems

Digital filters

  • recursive and non-recursive filters

Computer science

  • Encoding and arithmetics of numbers
  • Scaling of discrete controllers
  • A/D- and D/A-converters (quantization, principles of converters)

The lecture imparts the fundamentals of modern digital signal processing and analysis as required by today's data-processing systems in mechatronics. Furthermore, the students become acquainted with various methods for the synthesis of digital control loop systems. Another aim is to make the students detect the specific characteristics and effects of digital real-time systems for control, data acquisition and analysis and avoid negative effects, such as aliasing.
