Low order modeling, dynamics and control of an inert gas based fire protection system

We develop a three-parameter model for an inert-gas based fire suppression system. This consists of a two-parameter model for the discharge system coupled with a one-parameter model for the bulk dynamics in the room. We validate the model by predicting the mass discharge from the cylinder, overpressure in the room as well as temperature and pressure at a measurement location in the piping system. We develop an active control algorithm that achieves the objective of keeping the room overpressure under a specified value without significantly increasing the time of discharge relative to the uncontrolled case
