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 a ....etc

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

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

Abstract —
To avoid unexpected equipment failures and
obtain higher accuracy in diagnostic for the predictive
maintenance of induction motors, on-line health monitoring
system plays an important role to improve the system reliability
and availability. Among different techniques of fault detection,
work on motor current signature analysis by using only stator
current spectra has been well documented. In addition, the
recent developments in MEMS technology shows increasing
trend in integrating vibration analysis for fault diag ....etc

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 protec ....etc
