Abstract
Problem statement: This study presents an application of Indirect Adaptive Generalized Predictive Control (IAGPC) of an incubator for newborn, in order to improve the performance of temperature control. Approach: Analysis of physical phenomena of incubator was involved together knowledge of the dynamic behavior. Incubator was identified by means of Recursive Least Square (RLS) technique associated with a projection of the model parameters for robust system identification. Results: Results showed that mathematical model of neonatal incubator predicted coincide with the measured data. A comparative study was made between ON-OFF, PID and IAGPC control in order to provide the performance of each strategy. Conclusion: Results had proved effectiveness of the IAGPC as a control of incubator system.
Highlights
The First Published Report of an Incubator for use in the care of the premature infant by Thomas et al (1857) At this time, he had the idea to run a cradle zinc called incubator, in which it was possible to maintain a constant heat and to keep the baby warm
Temperature is one of the most important factors that need to be maintained with minimum variation to keep the transpidermal respiratory and water loss to a minimum level and to increase the heat storage body (Bach et al, 1999)
The current commercial devices use a classical control as the on-off or PID control (Thomas, 1999)
Summary
The First Published Report of an Incubator for use in the care of the premature infant by Thomas et al (1857) At this time, he had the idea to run a cradle zinc called incubator, in which it was possible to maintain a constant heat and to keep the baby warm. Temperature is one of the most important factors that need to be maintained with minimum variation to keep the transpidermal respiratory and water loss to a minimum level and to increase the heat storage body (Bach et al, 1999). At this time, the neonatal incubator keeps the newborn or premature infants in a suitable atmosphere in terms of temperature, humidity and oxygenation and protect, as much as possible from external aggression as germs and noise. The question remains if we use an advanced control strategy, we can be provide suitable environment for premature born infants and maintained the temperature that is set by the doctor without significant variation over time whatever disturbance
