This document presents the mathematical modeling and acquisition of a neonatal incubator thermal system representative transfer function with two modes of operation, depending to the system’s output variable (Air temperatura or infant skin’s temperature) that is under feedback and compared to the system’s reference input (The incubator heating temperature). It is shown the determined transfer function poles and zeros positions to both modes of operation, and the comparison of its frequency response characteristics to different kinds of functioning to one kind of the modes, as its time response of non linear and linearized system. The computer simulations were made with assistance of the Matlab® software.
