Models are used to describe the dynamic behaviour of a system, to predict future outputs of the system and are useful when designing certain control schemes. An effective control scheme could be used to influence the dynamic behaviour of a system in such a way that it exhibits more desirable dynamic behaviour. A control system could be designed to increase the efficiency of a system. This makes it obvious that accurate models are very useful. The focus of this study is to use Multiple-Input Single-Output (MISO) system identification techniques on data obtained from the Flownex simulation package. These techniques are used to obtain a (MISO) mathematical model for the Pebble Bed Modular Reactor (PBMR). MISO system identification techniques are used in this project to study the effect that the inputs have on each other. This information helps in the understanding of processes within the system. The reason for studying the MIS0 systems and not the Single-Input Single-Output (SISO) systems is because the field of interest focuses on the effects the inputs have on each other.
