This paper deals with the Sudden Infant Death Syndrome (SIDS) problem. The main objective is to limit it by controlling the main reasons that may lead to it. Sudden infant death syndrome is the death without specific reason of a healthy newborn, usually during sleep. Although the causes are unknown, SIDS may be related to abnormalities in the infant's brain that controls breathing and arousal from...
This paper proposes a method to control temperature over a finite diffusive interface using the CRONE controller. The second generation was chosen to be implemented in this paper as the plant model showed a constant phase margin when changing the metal constituting the diffusive interface media. As a result, an a posteriori synthesis method was established in order to control temperature at certain...
This paper presents the design of a regulator to control the temperature of a semi-infinite diffusive interface medium by using a unique robust controller for three different materials: aluminum, copper and iron. The second generation CRONE is used to control the temperature at the boundary where the density of flux is applied (i.e., x=0mm) as the parametric uncertainties (due to the copper and the...
The recognition of fractional order behavior when identifying physical systems is relatively new. One of these fields where the fractional order integration can show up is the thermal diffusive interfaces. In fact, for some special conditions, an integration of order 0.5 appears when identifying the system. So, the objective of this work, divided into two parts, is to study the presence and the effects...
After presenting, in the first part of this work, the homogeneous aluminum linear semi-infinite bar, and having shown that the fractional behavior of order 0.5 appears for relatively high instances which represents low frequencies (it depends in fact on the location of the temperature sensor), this part aims to do almost the same study but for a homogeneous aluminum linear finite bar. In this case,...
