ABSTRACT

Protection of an induction motor (IM) against possible problems, such as overvoltage, overcurrent, overload, overtemperature, and undervoltage, occurring in the course of its operation is very important, because it is used intensively in industry as an actuator. IMs can be protected using some components, such as timers, contactors, voltage, and current relays. This method is known as the classical method that is very basic and involves mechanical dynamic parts. Computer and programmable integrated circuit (PIC) based protect ....etc

CAN-based Synchronized Motion Control for
Induction Motors

Introducton
A control area network (CAN) based multi-motor synchronized motion control system with an advanced synchronized
control strategy is proposed in this article. adjacent cross-coupling control strategy is incorporated into into the sliding mode control architecture to achieve it.

Sliding-mode adjacent cross-coupling
control strategy of multi-motor synchronization:
Networked control system is flexible and expandable. to improve motion

Summary
The main objectives of this paper are to perform fault analysis on an induction motor using both experiments and simulation, and to study failure identification techniques applied for condition monitoring of the motor and finally to design an On-line condition monitoring system with fuzzy logic controller using LabView. The work in this paper was divided into two phases. The phase one was concerned with the modeling of three-phase induction motor in three phase reference frame using Matlab/Simulink and designing an i ....etc

Robust Adaptive Variable Structure Control Law

ABSTRACT
A novel sensorless adaptive robust control law is proposed to improve the trajectory tracking performance of induction motors. The proposed design employs the so called vector (or field oriented) control theory for the induction motor drives and the designed contro ....etc

ppt of street lightning based on sensors using plc and scada

Abstract

The man developed many more application for its convenience and luxury. All things change with technology. Man-made machines are going to be automotive to make it more efficient & to save electric power. In city areas, street lights are powered by the administrations & are controlled by man-made apparatus operated automatically. This is very common that street lights are Off in the daytime or sometimes at night due to unavailability of duty men. So this system was developed ....etc

PLC-Based Monitoring Control System for Three-Phase Induction Motors
The article presents a monitoring and control system design and implementation for the three-phase induction motor based on programmable logic controller (PLC) technology. the operational parameters of the motor is correlated with the the speed requested by the user by the PLC. This is done in both the during normal operation and under trip conditions. Tests prove that a higher accuracy in speed regulation is provided by the induction motor system driven by inverter an ....etc
