Model Predictive Control of Variable Speed Variable Pitch Wind Energy Conversion Systems
Abstract: A multiple-input, multiple-output model predictive control technique for variable-speed, variable-pitch wind turbines in the below-rated wind speed zone is proposed. The speed of the generator and power generated are regulated simultaneously by controlling the pitch angle of the wind turbine and the generator torque. This has the effect of extracting the maximum power from the wind for wind speeds below the rated value. Also, as the constraints are incorporated on …

Simulation of Flow Vorticity and Instability Analysis in a Solid Rocket Motor
Abstract: Combustion instability is a major problem in most solid rocket motor (SRM) during its operation. More form of instability is generated due to several factors like coupling of combustion acoustic waves with flow dynamics, grain configuration, combustion chamber design, combustible mixture, etc. This type of flow turbulence is sustained in such system for long durations and leads to failure of the mission. In this paper, an effort has been made …

Suitability of Additive Manufacturing Process in Optical Lens Production
Abstract: Additive Manufacturing is one of the non-conventional methods of manufacturing that is gaining immense popularity for its ease to manufacture customized parts. The lenses have always been manufactured using a continuous process of Blanking, Surface generation, Edging and Centering, Grinding, Polishing, and Coating. But the conventional processes demand large inventories and more time. Customization of lenses may also be possible if a process like Additive Manufacturing is implemented. Also, the …
