DIRECT TORQUE CONTROL FOR MATRIX CONVERTER-FED THREE PHASE INDUCTION MOTOR WITH HYBRID PSO
ABSTRACT
Direct Torque Control (DTC) for Induction Motors using Matrix Converters is a high performance motor
control scheme with fast torque and flux responses. This paper presents a new control scheme based on
hybrid particle swarm optimization (HPSO). The main advantages of the matrix converter are combines
with those of the DTC technique, generating the required voltage vectors under 0.9 input power factor
operations. The results ....etc

Modeling and Simulation of Speed of a Doubly Fed Induction Motor with Different Regulators
Many industrial applications require new control techniques in order to obtain fast response and to improve the dynamic performances. One of the techniques users, sliding mode,fuzzy logic and fuzzy sliding mode control which are characterizes by robustness and insensitivity to the parameters variation. In this paper, we present a comparative study of a direct stator flux orientation control of doubly fed induction motor ....etc

Diode Clamped Multilevel Inverter Fed Induction Motor


INTRODUCTION

Two level voltage source inverters produce an output voltage or a current with levels either 0 or ± Vdc

In high power and high voltage application these two level inverters, however, have some limitations in operating at high frequency mainly due to switching losses and constraints of device ratings.

Unique structure of ML-VSIs allow them to reach high voltages with low-harmonics wit ....etc

DOUBLY FED INDUCTION MACHINE

INTRODUCTION
ELECTRICAL MACHINES
Based on the supply, 2 types-AC machine & DC machine
AC machines are of different types
1. Induction machine
2. Synchronous machine etc.

INDUCTION MACHINE
Induction machines are of different types and one of the type in particular are Singly Fed and Doubly Fed.
SINGLY FED INDUCTION MACHINE
1. Only ONE winding active in ENERGY conversion Process
2. Can have speed around Synchronous Speed.

Field Orientated Control of a Multi-Level PWM Inverter Fed Induction Motorr
abstract
This thesis presents the simulation of a Field Orientated Control of a Multi level PWM Inverter fed induction motor system and its implementation in terms of programming and code in a real time operating system. Field Orientated Control allows precise controllability and excellent transient behaviour when used to control an induction motor by manipulating the angle and amplitude of the torque and speed producing curren ....etc
