this paper undertakes the synthesis of a logic-based switching h2/h∞ state-feedback controller for continuous-time lti singular perturbation systems. our solution achieves a minimum bound on the h2 performance level, while also satisfying the h∞ performance requirements. the proposed hybrid control scheme is based on a fuzzy supervisor managing the combination of two controllers. a convex lmi-b...

the main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. the reaction time and the rheological properties of samples during the polymerization were studied. the samples were characterized by thermo gravimetry analysis (tga), differential scanning calorimeter (dsc) and ft-ir spectrometer. the melt flow behavior and ...
