Abstract :
The modeling and identification of the thermoregulatory control system is considered, relating the thermal stimulus as input and heart rate variability as output of the system. The thermal stimulus is produced by using an entrainment device that is designed to provide hot and cold air at different frequencies covering the range of 85 to 805 (0.0125 to 0.125 Hz). This stimulus is directed by the entrainment device to the arm or leg through a plastic sheath for a period of 10 min. The thermal input as well as the heart rate variability signals as output are recorded by using power spectrum analysis. This work uses the algorithm of S.Y. Fakhouri (1980) to produce kernel identification of volterra series of the system. The model contains the linear part (first-order kernel) in parallel
