Simplified variable frequency induction-motor drive model for power system stability studies and control

An Embedded based Fuzzy System for Induction Motor Variable Frequency Drive

Induction motors are the most widely used for appliances, industrial control, and automation; however, many applications need variable speed operations. The rapid development of power electronics controllers in recent years has attracted the attention of researchers for making use of flexible characteristics of an induction motor in variable frequency drives. It presents a compact embedded fuzz...

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

A Novel Variable-Frequency Three-Phase Induction Motor Drive System Using Only Three Controlled Switches

This paper presents a novel variable-frequency motor drive system for a three-phase induction machine. In this drive system, the machine is excited by unidirectional stator currents shaped and sequenced such that a rotating air-gap flux is induced so that the machine can operate. Due to the unidirectional nature of the currents, an “inverter” that incorporates only three active, insulated-gate-...

Nonlinear Model Predictive Control for Induction Motor Drive

One of the most important development in control area for induction motor has been field oriented control (FOC) established firstly by (Blaschke, 1972). However, the performance of this technique is affected by the motor parameter variations and unknown external disturbances. To improve the dynamic response and reduce the complexity of FOC methods, an extension amount of work has been done to f...

FACTS Control Parameters Identification for Enhancement of Power System Stability

The aim of this paper is to investigate a novel approach for output feedback damping controller design ofSTATCOM in order to enhance the damping of power system low frequency oscillations (LFO). The design ofoutput feedback controller is considered as an optimization problem according with the time domain-basedobjective function which is solved by a honey bee mating optimization algorithm (HBMO...
