Speed Control of Induction Motor Using PLC and SCADA SystemIJERA Editor
Automation or automatic control is the use of various control systems for operating equipment such as

feed it back to the PLC, which compares to the desired value and take a control action, then the signal is
transferred to the motor – via driver – to increase / decrease the speed. We will measure the speed of the motor

IRJET- Monitoring of Distribution Transformer and its Theft Protection by...IRJET Journal
This document discusses a system to monitor and protect distribution transformers using programmable logic controllers (PLCs). The proposed system uses PLCs, relays and sensors to monitor parameters like voltage, current, temperature, oil level and detect faults in the transformer like overloading, overvoltage, undervoltage and overheating. It aims to automate monitoring of distribution transformers which are important power system equipment but often not properly maintained, leading to reduced efficiency and power interruptions. The system continuously monitors transformer parameters through sensors and takes action by shutting it down if faults are detected, making distribution systems more reliable and efficient.
Speed Control of Induction Motor Using PLC and SCADA SystemIJERA Editor
Automation or automatic control is the use of various control systems for operating equipment such as
machinery, processes in factories, boilers and heat-treating ovens, switching in telephone networks, steering and
stabilization of ships, aircraft and other applications with minimal or reduced human intervention. Some
processes have been completely automated. The motor speed is controlled via the driver as an open loop control.
To make a more precise closed loop control of motor speed we will use a tachometer to measure the speed and
feed it back to the PLC, which compares to the desired value and take a control action, then the signal is
transferred to the motor – via driver – to increase / decrease the speed. We will measure the speed of the motor
using an incremental rotary encoder by adjusting parameters (PLC, driver) and also we need to reduce the
overall cost of the system. Our control system will be held using the available Siemens PLC. In addition, we will
monitor motor parameters via SCADA system.
This document describes a project to monitor and control the speed of an electric motor using a variable frequency drive (VFD) via wireless technology and the Internet of Things (IoT). A VFD controls the speed of a motor by varying the frequency and voltage of the input. Typically, VFDs are controlled on-site, but this project integrates the VFD with the internet using a Texas Instruments CC3200 microcontroller to allow remote monitoring and control of the motor speed via a mobile application. Real-time motor speed data can be monitored from remote locations and stored in the cloud for analysis. The goal is to provide a non-physical means of controlling and monitoring VFDs and motor speed wirelessly.

IRJET- Direct Torque Control of Induction MotorIRJET Journal
This document summarizes direct torque control of an induction motor. It discusses using a direct torque control strategy to control an induction motor by implementing a switching table, torque and flux estimators, and a space vector modulation block. The control system measures motor currents, voltages and speed, performs Clarke and Park transformations, and estimates torque and flux. Torque and flux errors are fed to hysteresis controllers to select appropriate inverter switching vectors. Simulation results show the motor speed reaches the reference speed of 1000 rpm smoothly and torque settles to a steady value. Direct torque control provides improved torque control over older field oriented control and reduces torque and flux ripples.

This document provides a comparison of scalar and vector control techniques for controlling the speed of three-phase induction motors. It presents the modeling and simulation of scalar and vector control methods for an induction motor drive using a two-level inverter in MATLAB/Simulink. The scalar control technique is simpler to implement but provides lower performance compared to the vector control technique. Simulation results show that vector control reduces torque ripple and lower order harmonics compared to scalar control, providing better speed regulation and power quality. Vector control also offers faster dynamic response making it suitable for applications with frequent load changes.

FOUR QUADRANT SPEED CONTROL OF DC MOTOR USING AT89S52 MICROCONTROLLERJournal For Research
Speed control of a machine is the most vital and important part in any industrial organization. This paper is designed to develop a four quadrant speed control system for a DC motor using microcontroller. The motor is operated in four quadrants i.e. clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions. In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this proposed system is very apt as forward brake and reverse brake are its integral features. Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with the PWM pulses generated by the microcontroller. The microcontroller used in this project is from 8051 family. Push buttons are provided for the operation of the motor which are interfaced to the microcontroller that provides an input signal to it and controls the speed of the motor through a motor driver IC. The speed and direction of DC motor has been observed on digital CRO. Microcontroller programming has been written in assembly language by using notepad and it has been converted in hex file by using micro vision Kiel. The burning of programming in the 8051 microcontroller chip has been done by using positron boot loader software.

A Novel Rotor Resistance Estimation Technique for Vector Controlled Induction...IAES-IJPEDS
Induction motor with indirect field oriented control is well suited for high
performance applications due to its excellent dynamic behavior. However it
is sensitive to variations in rotor time constant, especially variation in rotor
resistance. In this study a scheme based on the Rotor flux Model Reference
Adaptive Controller is used for on line identification of the rotor resistance
and thus improving the steady state performance of the drive. The overriding
feature of this estimation technique is the accurate identification of rotor
resistance during transient and steady state conditions for drive operation at
full load and at zero speed condition. Moroever, the effectiveness of the TS
fuzzy controller utilizing rotor flux for online estimation of rotor resistance
for four quadrant operation of motor drive is investigated and compared with
the conventional PI and Mamdani fuzzy controller.Simulation results in
MATLAB/Simulink environment have been presented to confirm the
effectiviness of the proposed technique.

Arm cortex (lpc 2148) based motor speedUday Wankar
The project is designed to control the speed of a DC and AC motor using an
ARM7 LPC2148 processor. The speed of motor is directly proportional to the voltage
applied across its terminals. Hence, if voltage across motor terminal is varied, then
speed can also be varied. This project uses the above principle to control the speed of
the motor by varying the duty cycle of the pulses applied to it, popularly known as
PWM control. The project uses input button interfaced to the processor, which are
used to control the speed of motor. Pulse Width Modulation is generated at the output
by the microcontroller as per the program. The program is written in Embedded C.
The average voltage given or the average current flowing through the motor
will change depending on the duty cycle, ON and OFF time of the pulses, so the speed
of the motor will change. A motor driver IC is interfaced to the ARM7 LPC2148
processor board for receiving PWM signals and delivering desired output for speed
control. Further the project can be enhanced by using power electronic devices such
as IGBTs to achieve speed control higher capacity industrial motors.

Servo motors are important for improving accuracy in industrial machines. Servo motors use encoders with high resolution of up to 24 bits for precise positioning. Features of servo drives like vibration suppression and motor ripple compensation help improve machine accuracy. Using high-speed Ethernet networks of 125 microseconds between controllers and servo drives also enhances accuracy when controlling servo motion. A variety of servo motor types exist, including rotary, direct drive, and linear motors, which are chosen based on the machine's needs. Achieving high accuracy requires consideration of factors like motion control, feedback encoders, and compensation for mechanical properties.
