FLUX ESTIMATORS FOR SPEED-SENSORLESS
INDUCTION MOTOR DRIVES
Abstract
This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance
the stability and the performance of state-of-the-art sensorless drives, new flux estimator
designs based on the standard motor model are proposed. Theoretical and experimental
research methods are both used. The dynamics and stability of flux estimators
are analyzed using linearized models, and the effects of parameter errors are investig ....etc

Every kW of energy saved is as good as same amount of energy generated. Such is the scarcity of energy in India. Energy can be saved by using Variable Speed Drives (VSD) for applications like Pumps and Fans. Employing conventional techniques, which uses a motor running at full speed and flow pressure being created by throttle valve, a lot of energy is wasted due to electric, thermal and mechanical losses. By replacing conventional arrangement with AC drives, tremendous amount of energy can be saved. However, traditional approach to flow control ....etc

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 drop and slip frequency. The scheme proposed fully compensates for ....etc

Variable Voltage And Variable Frequency drives
Presented By:

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

Doubly-Fed Induction Generator for Variable Speed Wind Energy Conversion Systems- Modeling & Simulation
Abstract The aim of this paper is to present the complete modeling and simulation of wind turbine driven doubly-fed induction generator which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. The grid side converter controls the power flow between the DC bus and the AC side and allows the ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES
Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same speed.

Direct torque control (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors. This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor. ....etc
