SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES



ABSTRACT :

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance d ....etc

EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC MOTOR



The project ‘’EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC
MOTOR’’ is used to varying Speed of The dc motor. It is need a DC to DC converter
is a Circuit Which converts a source of direct current (DC) from one voltage Level to
Another.
Linear regulators output can only in low in low voltage From the Input.
They are very inefficient if the voltage drop is large and the Current high as they
dissipate as heat, a power equal To the product of the output current and ....etc

After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps is that RF lamps operate without electrodes .There are three practical ways to energize RF light sources, though there are more ways to create RF plasmas. These three ways correspond to different types of interaction of electroma ....etc

RFID systems have been sued in numerous applications like asset tracking, toll collection and libraries. The following seminar presents our on going research for the Auburn University Detection and Food Safety (AUDFS) project to use RFID technology combined with sensors for detection of pathogens in food. AUDFS aims to integrate the breakthrough in the detection of food borne illnesses with advances in wireless and biosensor technologies. The goal of the research is a system that can keep track of food products from initial production throughou ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

Remote device control using Radio Frequency


The project compares the communication of control signals using radio frequency
and Infra Red Rays. The STR is ideal for short-range remote control applications where
cost is a primary concern. The receiver module requires no external RF components
except for the antenna. It generates virtually no emissions, making FCC and ETSI
approvals easy. The super-regenerative design exhibits exceptional sensitivity at a very
low cost. A SAW filte ....etc

Definition

RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps and conventional lamps is that RF lamps operate without electrodes .the presence of electrodes in conventional florescent and High Intensity Discharge lamps has put many restrictions on lamp design and performance and is a major factor limiting lamp life.

Recent progress in semiconductor power switching electronics, which is revolutionizing many facto ....etc
