New algorithms, high data volumes and the increasing use of artificial intelligence in machine control require a completely new performance class of embedded control systems as well as new methods for the design and testing of control software.
The Distributed Computing and Communication group is characterized by a broad spectrum of competencies - from the design of microelectronic integrated circuits and architectures to the development of hardware-related software, the integration of sensors and actuators, and the networking of electronic control systems.
Special competencies already exist in the subject areas:
- Energy efficiency
- real-time capability
- Safety and security
- sturdiness
- Hardware/Software Architectures
- System partitioning, modelling and simulation
In production plants, the products often go through many successive processing steps, which take place on different machines and positions in the shop floor. In order for these processing steps to be carried out in a coordinated manner, the control devices must be able to communicate reliably with each other. Therefore, secure communication procedures and architectures are a central object of research for the DCC Group.
The most diverse requirements, such as compatibility with industrial standards, reaction times and bandwidths, as well as safety and security, play an important role in the design. The group is therefore researching processes and methods for developing efficient solutions for the various communication requirements of production systems.
The FAVIA reference platform is being developed in the DCC group as a research platform and concept for future architectures of automation technology. It enables the testing of new approaches for control and automation tasks. At the same time, it allows a smooth transition from prototypes to productive systems.
