First-order Systems Simulator

First-order systems are among the simplest dynamic models used in process engineering, yet they capture the behavior of many real processes surprisingly well. They are characterized by a single dominant time constant that determines how quickly the process responds to a change in its input.

This simulator allows the response of a first-order system to be explored interactively, making it easier to visualize concepts such as process gain, time constant, transient response, and the gradual approach toward a new steady state.
