Abstract

Objectives: The scope of this work was to: 1. to fabricate Silicon Carbide (SiC) particle Metal Matrix Composites (MMC) by vortex method; 2. to investigate the effect of SiC particles on the tensile and impact behavior of SiC particle reinforced 6061 aluminum alloy composites. Recently, the material technology has seen many contemporary developments in the field of fabricating new materials which reinstates the current materials for different applications. Amidst these, the composite materials have an important aspect which is a combination of different materials possessing various physical and chemical properties. Methods: This Aluminum base metal Matrix Composite (AMC) has been manufactured by wrought aluminum alloy by varying the weight fractions of silicon carbide to compose five distinct forms of composites. Stir – casting has been chosen as the manufacturing technique, in this study. Findings: The manufactured composites were tested to determine their tensile and impact properties and the result proves that the sample with higher percentage of silicon carbide has better mechanical properties, comparably. Applications: This study essentially focuses on establishing AMC as they find applications on aerospace and automotive industries because of their admirable properties compared with the unreinforced alloys.

Abstract

Objective: The objective is to design PSO based I-PD Controller and PID Controller for a nonlinear system. The nonlinear system selected is Interacting Spherical Tank System. Methods: Controlling of a nonlinear system is an important process. The PID Controller and PSO based I-PD controller are designed for the non linear systems selected and the error values are calculated. The comparison of performance between these two controllers is done and result is produced. Findings: From the simulation result it is inferred that PSO based I-PD controller gives smooth response when compared to PID controller whereas error indices are less in PID controller. Applications: The spherical Tank is widely used in petrochemical industries, paper making industry, water treatment industries.
