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 d ....etc

Abstract
The matrix converter is superior to the P W inverter drives because of its regeneration ability and sinusoidal input current. Therefore, it meets the stringent energy-efficiency and power quality requirements of the new century. This paper describes the basic operating principles and control method of the matrix converted; and reports the detailed experimental operating characteristics of an I1 kVA matrix converter drive over its full operating range. Through the experimental operating characteristics, t ....etc

In this work, Matlab/Simulink modeling and simulation of the three - phase matrix converter feeding a passive RL load have been performed using the space vector control algorithm. The model has been designed to support real time implementation with a simulation supported DSP control board. The algorithm uses a simpler method than the other control algorithms to control the input power factor. In addition, it has lower switching loses and easy implementation. Simulation has been implemented for various output frequencies at unity input power fac ....etc

For industrial and mining applications, 3-phase AC induction motors are the prime movers for the vast majority of machines. These motors can be operated either directly from the mains or from adjustable variable frequency drives. In modern industrialized countries, more than half the total electrical energy used in those countries is converted to mechanical energy through AC induction motors. The applications for these motors cover almost every stage of manufacturing and processing.

Applications also extend to commercial buildings and the do ....etc

Its a new control algorithm for a matrix converter (MC) induction motor drive system. a new switching strategy, which applies a back-propagation neural network to adjust a pseudo dc bus voltage, to reduce the current harmonics of the induction motor, and a two-degree-of-freedom controller is to improve the system performance. The controller design algorithm can be applied in an adjustable speed control system and a position control system to obtain good transient responses and good load disturbance rejection abilities. The im ....etc

Abstract
This paper describes a generalid simulation model of the three-phase induction motor using the SIMULIMC software package of MATLAB. The model is based on two-axis theory of revolving frame transformation. The model takes power source and load torque as inputs and gives speed and electromagnetic torque as outputs. Internal resistance of the power supply and magnetic saturation of the motor may also be accounted for.

ABSTRACT:This paper proposes design and simulation of a direct torque controlled induction motor drive system based on space vector modulation technique for ripple reduction.Direct Torque Control is a control technique used in AC drive systems to obtain high performance torque control. The principle is based on simultaneously decoupling the stator flux and electromagnetic torque. DTC drives utilizing hysteresis comparators suffer from high torque ripple and variable switching frequency.The ....etc
