Generating Fuel Energy by Catalytic Pyrolyzing of Microalgae
Abstract: In biomass pyrolysis process, a catalyst is used to modify the pyrolysis gases' chemical composition and increase the bio-oil fraction. This process uses the byproducts of thermal conversion processes. It is anticipated that the introduction of pyrolysis catalysts in the case of microalgae will lower the bio-oxygen oil's content and increase the number of added-value compounds in this liquid fraction. Catalysts can also help decrease the nitrogen in bio-oil. As …

Design And Implementation of Controllers for Quadruple Tank System
Abstract: Process industries have tightly integrated processes which are non-linear and have multiple manipulated and controlled variables. Level measurement plays an important role in many industries. In this paper, the level of the two lower tanks has to be controlled. Three different controllers have been designed and implemented by manipulating the motorised control valve. Conventional controllers may not perform well because of the variations in process dynamics and disturbances around them. …

Speed Control of An Inverter Fed Three-Phase Induction Motor Using IP Controller Considering Core Loss and Stray Load Loss
Abstract: Consideration of core losses and stray load losses to design a controller of an inverter fed induction motor are affected to the flux and torque decoupling strategy adversely. As a consequence, the detuning of field-oriented control (FOC) is required. The detuning strategies have been developed in some literatures. But the implementation of detuning becomes difficult because of higher order expression. In general, the controlling and estimation of AC drives are …
