Steady-state response

Definition

Steady-state response refers to the behavior of a dynamic system after it has settled and is no longer influenced by initial transients, effectively showcasing how the system reacts to continuous inputs. This concept is crucial in understanding how systems stabilize over time, particularly in maintaining performance under small disturbances and variations. By analyzing steady-state response, engineers can design controls that ensure stability in systems like microgrids or during dynamic simulations.
