DESIGN AND IMPLEMENTATION OF PID CONTROL
BASED BABY INCUBATOR
Premature babies are babies born under the age
less than 37 weeks weighing 2500 g. Premature
babies have thin skin and shiny. Therefore,
premature babies have difficulty maintaining a
constant body temperature [1]. In order to grow like
other normal babies, they should be immediately
put in a baby incubator with temperature ranges
between 32-37°C.
Baby incubators available on the market are
using on-off control on the heating system to
control the temperature in the incubator. This
method has the disadvantage of the transient
response time of the position of living long enough
from the off position or conversely, and requires a
large enough power to turn on and turn off the
heater continuously.
To overcome this, we need a method to control
the temperature in order to further conserve power,
which is in this paper we use Proportional- Integral-
Derivative (PID) control. PID control technique is
likely to get a response that has a high degree of
stability so that it can more accurately control the
temperature and save energy compared to using the
on-off control [2].
The purpose of this research is to design a baby
incubator system with the capability of monitoring
and controlling its temperature effectively using
PID control.
In this paper, we implement PID control to a
baby incubator with following specifications: set
point is set to 320 C, using ATmega328 in Arduino
UNO R3 board, power maximum of the heater is
250 W and reference temperature is the temperature
read from a temperature sensor SHT11.
