Signal Modeling, Control and Simulation of Boost Converter Using PV Cell
Abstract: DC-DC converters are switched power converters. They are used to convert one DC voltage to another DC voltage. It is inordinately used in industry as well as in research. The model of the converter system varies from the ON state to the OFF state. The major drawback of the boost converter is the uncontrolled supply of voltage and current. So, a convectional PID controller is designed to regulate the output …

Performance and Analysis of PI Controller using Characteristic Ratio Assignment Method for Coupled Tank Process
Abstract: Control the level of the liquids is a critical need in many industrial processes. Often the tanks are so coupled together that the levels interact and exhibits a nonlinear behaviour. Control of coupled tank system using conventional PI controller, result in poor performance. In this paper the modelling and controller design for coupled tank liquid level process using characteristic ratio assignment (CRA) method is implemented. CRA method is an approach …

Design and Fabrication of Agriculture based Product Filling and Packing Machine
Abstract: In earlier days, filling and packing was done manually; a person had to weigh the product using some means like weighing balance and then fill it to a container and then pack it. This takes lots of labor and time which is the key factor in the mass production as well as in batch production. To reduce the man power in packing field and to increase the productivity, this concept …

Distinctive Approaches for Improving the Aqueous Solubility of BCS Class II Drugs
Abstract: The most difficult feature of many novel chemical entities is their solubility behaviour, as 60 percent of new promising products suffer solubility limitations. This is the most common reason for novel medicine compounds failing to reach the market or performing to their full potential. The proportion of the aqueous phase when the solution is in equilibrium with the pure substance in its normal phase is referred to as aqueous solubility. …
