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.

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.

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
