Kontrollfelter

Kontrollfelter is a term used in Norwegian and Swedish that translates to “control fields” in English. It refers to fields, inputs, or elements that regulate or influence a system, device, or software. The exact meaning depends on the context, but the core idea is that the field exerts control over some process or behavior.

In control theory and automation, a kontrollfält describes the input signals that drive a system, such as a plant. The controller computes a control law to adjust these fields in order to achieve a desired state or trajectory. These fields are often represented as signals like u(t) and can control variables such as voltage, torque, or flow setpoints in industrial processes.

In computing and information technology, control fields are user interface elements that let users influence how an application behaves. Typical controls include checkboxes, sliders, radio buttons, and drop-down menus. They gather input, configure settings, filter results, or drive workflows. In databases and forms, such fields help capture data and can enforce constraints or validation rules.

In data collection and validation contexts, control fields help ensure data integrity by enforcing constraints, cross-checks, or derived values. For example, a password confirmation field acts as a control to verify that the user intended input matches a separate field.

Terminology note: the term is a loan translation used in Scandinavian languages. In English, “control field” has broad usage across engineering, computing, and data-processing domains. See also control theory, user interface controls, and form fields.
