Digital Control Systems

Lecture-No.:

105311 / 105312 / L.10452250 / L.10452450

Type of course:

Lecture (2 SWS), Excercise (1 SWS)

Schedule:

The event takes place in the summer term and the winter term.

Current schedule of events will be announced in Paul.

Target group:

Students of mechanical engineering, electrical engineering, technomathematics, industrial computer sciences, computer sciences, master.

Requirements / foundation:

Control Engineering, desirable Advanced Control Engineering (formerly Control Engineering 2)

Content:

Functioning of digital control

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

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
• Digital frequency response, spectrum

Digital filters

• recursive and non-recursive filters

Computer science

• Encoding and arithmetics of numbers
• Quantization, scaling of discrete controllers
• A/D- and D/A converters

Lab practice - Measurement of typical effects of digital systems

Objectives:

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.
