This paper focuses on the efficient control of a photovoltaic device's voltage. Under irradiation variation and constant load, a robust controller is proposed. The second-order sliding mode controller for buck converter based on super twisting algorithm is designed to ensure both the reliability and robustness of the global system. The proposed control strategy's reliability is demonstrated by experimental results using dSpace 1104.

This paper presents MRAS speed sensorless control of induction motor using type-2 fuzzy logic controller (T2FLC). These controllers replace the PI ones, in the new MRAS strategy proposed in Benlaloui et al. (IEEE Trans Energy Convers 30(2):588–595, 2015), in order to improve the induction motor performances and robustness at low speed region. Indeed, the choice of these controllers is made because of their adaptation-based schemes which permit to handle nonlinear uncertain systems without the need of precise mathematical model required when using PI controllers. Comparative study had shown a better rejection of disturbance and high insensitivity to stator resistance compared to the PI and the T1FLC controllers. The effectiveness of the proposed speed-based T2FLC estimation method and its good robustness are validated by simulation and by experimental results.

New 2-pyridone derivatives were hemi-synthetised in situ using essential oils of endemic Algerian plants; Ammodaucus Leucotrichus and eucalyptus citriodora as source of chiral aldehydes (perillaldehyde and citronellal respectively). The one pot reaction was carried out in Ethanol including cyanoacetohydrazide, essential oil, and malononitrile. The reaction mixture was catalysed by potassium carbonate. In the present work, two new compounds of highly functionalized 2-pyridones were obtained as privileged medicinal scaffolds. The structures of 2-pyridone derivatives were confirmed by 1H NMR, 13C and 2D
