Closed-Loop Modeling and Related Problems of Embedded Control Systems in Engineering

The contribution tries to present some issues coming from control technology in a way that is related to embedded or reactive systems in computer science and technology. It therefore reviews some of the very basic design patterns of control engineering and shows the differences and similarities of the control engineering approach and methodologies taken from computer science and technology. It focuses on development of closed-loop and model-based design patterns for Programmable Logic Controllers for discrete state/transition or even hybrid systems. Some of the major issues in this field are discussed. Current limitations and obstacles are highlighted, and some ideas about how they could be overcome in future are presented.
