ADAPTIVE FUZZY FAULT-TOLERANT CONTROL OF UNCERTAIN FRACTIONAL-ORDER NONLINEAR SYSTEMS WITH SENSOR AND ACTUATOR FAULTS

Adaptive Fuzzy Fault-Tolerant Control of Uncertain Fractional-Order Nonlinear Systems with Sensor and Actuator Faults

In this work, an adaptive fuzzy backstepping fault-tolerant control (FTC) issue is tackled for uncertain fractional-order (FO) nonlinear systems with sensor and actuator faults.A fuzzy logic system is exploited to manage unknown nonlinearity.In addition, a novel FO nonlinear filter-based dynamic surface control Steam Iron (DSC) method is constructe

Modeling of asphaltene precipitation - part I: comparative study for asphaltene precipitation envelope prediction methods

The solubility of asphaltenes in crude oils is predominantly influenced by variations in temperature, pressure, and oil composition.These alterations can precipitate asphaltene deposition, resulting in diminished permeability, obstruction of wells and auxiliary surface facilities, and ultimately, a reduction or cessation of production.Therefore, it

Ca2+ mobilization-dependent reduction of the endoplasmic reticulum lumen is due to influx of cytosolic glutathione

Abstract Background The lumen of the endoplasmic reticulum (ER) acts as a cellular Ca2+ store and a site for oxidative protein folding, which is controlled by the reduced glutathione (GSH) and glutathione-disulfide (GSSG) redox pair.Although depletion of luminal Ca2+ from the ER provokes a rapid and reversible shift towards a more reducing poise in
