High Performance Temperature Controller For Infant Incubators

Temperature is one of the most important parameters that need to be maintained to provide suitable environment for infants especially premature born infants. It is important that the temperature that is set by the doctor is maintained with out significant variation over time. The product that has been developed here uses proportional and integral controllers together with pulse width modulation and switching to provide accurate temperature maintenance with reference to the input temperature. This paper provides an overview of the temperature control system developed and explains the techniques used in the optimization of the temperature regulation within plusmn0.1degC. It further discusses the safety methods used and the sensor that is used in order to get the required temperature feedback for the control.
