stimulates creativeness, research and growth in the area of in Electronics and Communication

Systems.

The development and growth of the mankind is the consequence of brilliant Research done by

eminent Scientists and Engineers in every field. RTECS provides an outlet for Research findings and

reviews in areas of Electronics and Communication found to be relevant for National and

International recent developments & research initiative.

The aim and scope of the Journal is to provide an academic medium and an important reference for

the advancement and dissemination of Research results that support high level learning, teaching and

research in the domain of Electronics and Communication.

Finally, I would like to thank Editors and Authors for their continued support and invaluable

contributions and suggestions in the form of authoring. I express my sincere gratitude and thanks to

A Fuzzy Theory-Based Control of a Chopper-Controlled

Converter DC Machine Drive

Sona Chahal*, Sandhya Gupta, Sakshi Jindal, Pallavi Saxena, Yashi Vashishtha Department of Electrical and Electronics Engineering, Lord Krishna College of Engineering,

Ghaziabad, Uttar Pradesh, India

Abstract A fuzzy controller is designed for closed loop control of Chopper controlled generator load coupled separately excited DC motor and presented in this paper. This system has

been designed to have two loops with an inner fuzzy current controller and an outer fuzzy

speed controller. A linear model of closed loop system is developed by using small perturbation technique including the effect of generator load, the armature reaction and

the chopper commutation time. A trapezoidal method is used to estimate the chopper

commutation time. The transient responses of the system are obtained by using the matlab simulation. The performance in respect of voltage variation or load variation and speed

change has been obtained. The performance of the proposed controller is compared with the classical control results and found that the fuzzy-based Chopper controlled generator

load coupled separately excited DC motor has better results.

Keywords: conjunction, disjunction, fuzzification, defuzzification, electric motor

Digital Communication Receiver CMOS Chip Design

Shipra Suman* VLSI Designing, Banasthali Vidyapeeth, Rajasthan, India

Abstract RF receivers are such electronic devices that discrete radio signals from one another and

transform specific signals into respective audio, video, or data formats. It uses an antenna to receive transmitted radio signals and a tuner to separate a specific signal

from all of the other signals that the antenna receives. Detectors or demodulators at that moment extract information that was programmed formerly to transmission. There are

numerous customs to decode or modulate information.

Keywords: CMOS, amplitude modulation (AM), frequency modulation (FM),

amplitude shift key (ASK), frequency shift key (FSK), phase shift key

Satellite Tracking with Orbitron Software

Durgesh Baraithya*, Madhav Singh Electronics Engineering Department, Madhav Institute of Technology & Science, Gwalior, India

Abstract Satellite communication is used for telecommunications to make link globally. Satellite

tracking is used to find out the position of satellite or its orbits. With the help of tracking software like orbitron it is easy to track. In this paper we will discuss satellite tracking

with software which will help us to know about of satellite’s position for given moment and also about its orbital parameters. Today, several satellite-tracking programs are

available in shareware or for purchase, as well as in a variety of different computer

formats like orbitron software.

Keywords: tracking, very high frequency, ultra high frequency, orbitron, VO-52
