The Textbook Stops Here.

The default settings are designed to be challenging — an integrating process under heavy chaotic disturbance that will test even experienced engineers. But the simulator is fully configurable. You can enter your own process parameters for both FODT and Integrating with Lag and Dead Time processes, making it a practical tool for studying the dynamics of a specific real-world loop. Reduce the disturbance amplitude and increase the update steps, and the chaos gives way to something closer to low-level noise. Set the amplitude to zero and the disturbance disappears entirely. At that point you have a clean, readily accessible process simulator available in your browser whenever you need it, with no software to install and no IT department to negotiate with. One practical note on scaling: the simulator operates on a -5 to +5 range as a screen convenience. Zero represents steady state. To simulate an actual process, scale your real-world process parameters and signals to that range. The dynamics and the tuning challenge remain the same. Start with the default settings if you want a challenge. Dial them back when you want a tool.
