dödtidsfunktion
The term *dödtidsfunktion* (Swedish for "dead time function") refers to a concept in control theory and signal processing that describes the delay in a system's response to an input signal. In control engineering, dead time arises when a system's output does not change immediately in response to changes in the input, but rather exhibits a measurable delay. This phenomenon is common in processes involving physical transport, such as chemical reactors, heating systems, or mechanical conveyors, where signals or actions must propagate through a medium before taking effect.
Dead time is distinct from pure time delay, which is a fixed, constant delay, and from other
In control system design, dead time poses challenges because it can destabilize feedback loops, leading to
Dead time is also relevant in communication systems, where signal propagation delays in networks or cables
