Modelling and H∞ Robust Control of a Neonatal Incubator
Abstract: This study presents the modelling of a neonatal incubator and the design of a robust H∞ controller. Neonates, who are born premature, often don’t have enough maturity to regulate their temperature. These infants have low metabolic heat production rate and may have high heat loss from the skin so they have an increased risk of death in the first week of their life. The core temperature of the human body …

A Sliding Mode Control with a PID Sliding Surface for Power Output Maximizing of a Wind Turbine
Abstract: The wind energy has many advantages, it does not pollute and it is an inexhaustible source. However, thecost of this energy is still too high to compete with traditional fossil fuels, especially on the less windy sites.The performance of a wind turbine depends mainly on three parameters: the power of the wind, the powercurve of the turbine and the generator’s ability to respond to the wind fluctuations. This article proposes …
