Steuerteil

Steuerteil is a German term used in engineering to denote the portion of a system that performs the control function, i.e., it processes input signals, compares them with reference values, and determines the actions needed to achieve a desired state. It is a central component of many closed-loop control architectures and is often discussed in contrast to the measuring part (Messglied) and the actuating part (Stellglied).

The exact scope of the Steuerteil varies by field and author. In some contexts it refers specifically to the computational and decision-making element, such as a control unit or software module that implements control algorithms. In other contexts the term is used more broadly to include both the electronic or software logic and, in mechanical systems, the associated control interfaces. Because of this variability, many texts prefer related terms like Steuergerät or Steuereinheit for explicit reference to the control unit.

Functions and implementations: The Steuerteil typically receives data from sensors, processes this information according to a control law, and outputs control signals to actuators. Realizations range from embedded controllers and programmable logic controllers to dedicated control units in automotive, industrial, or robotic systems. In automotive technology, for example, the Steuerteil may govern steering, braking, or driver-assistance functions by issuing commands to Stellglieder based on sensor inputs and control objectives.

Note: The term is technical and its precise meaning is context-dependent; readers should consult discipline-specific sources to determine the intended scope in a given text.
