A model of the controller responses of the human temperature regulating system to changes in water temperature

The objective of this study is to develop models of the controller mechanism of the human temperature regulating system in a water environment . Both univariate and transfer function models are developed for metabolic heat production, and a mean squared error criterion is used to compare the performance of the two models. The models developed for the controller mechanism are validated in the context of a complete simulation model which is modified to include the controller model derived in this study. The results of the validation procedure show that the controller model is statistically valid.
