Real-Time Simulation with HiL internship

Lecture-No.:

L.104.52286

Type of course:

Lecture (2 SWS)

Schedule:

The event takes place in the winter term.

Current schedule of events will be announced in Paul.

Target group:

Students of mechanical engineering, industrial computer sciences, industrial engineering, technomathematics and computer sciences.

Requirements / foundation:

required: Control Engineering, Simulation Technology

advisable: Digital Control Systems

Content:

Components of a HIL test bed

• real-time systems (dSPACE, Testrig), actuators, measuring devices, etc.

Components of a real-time system

• interfaces to the testbed: A/D-, D/A-converters, digital I/O, digital and analog filters
• control algorithm: discretisation, numerical integration methods

Actuators for an HIL testbed 

• demands on the actuators: bandwith, power, linking to real-time system, etc.
• electric motors and hydraulic actuators

Analog and discrete signal processing

• aliasing, bandwidth, phase, stability

Lab tests 

• measurement of typical effects of digital systems
• optimal realisation of digital controllers and filters

Objectives:

On the basis of the contents of the "Simulation Technology" lecture the aspects of simulation under real-time conditions will be treated. The special features of real-time simulation will be analyzed by means of actual hardware-in-the-loop test beds (HIL test beds), possible realization will be discussed and then implemented. As the Chair of Control Engineering and Mechatronics employs modern HIL test beds also for testing new actuators, the lecture will not only deal with the specific properties and effects of digital real-time systems, such as aliasing, quantissation, and aptimal discretisation, but also the requirements on force actuators (electric motors, hydraulic cylinders, etc.) necessary for an HIL test bed.
