Design and Construction of DC Motor Speed Controller Using Android.pptEEESrproject
Rapid progress in microelectronics and microcontrollers in recent years has made it possible to apply modern control technology to control efficient and reliable operation of many applications such as the engine, anti-lock braking system (ABS), cruise, steering, and vehicle traction. Many of these operations including DC motor and therefore there is a need for implementing effective control strategies with digital control of these motors. The speed of DC motor is directly proportional to armature voltage and inversely proportional to field flux and adjustable speed drives can be operated over a wide range by controlling armature or field excitation. Development of various solid state switching devices such as diode, transistor and thyristor along with various analog/digital chips used in firing/controlling circuits, have made dc drives more handy for control in numerous areas of applications. For DC motor speed control, closed-loop PWM technique is widely used and well known . In this technique, the regulation of motor’s speed is realized by changing the voltage of motor which is adjusted by the duty ratio of PWM. In order to improve the performance of motor’s speed regulation and to reduce the steady-state error of the rotational speed of motor, a high- performance microcontroller can be used.In this work, an arduino microcontroller is used for implementation.
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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Abstract: Wireless technology is rapidly growing in many industrial applications like
monitoring, control and coordinates production in industrial aspects. Variable Frequency Drives
(VFD) are the most important device used in all modern industries, used to operate and control
the motors in industry at different speed depending on the requirement of the process of the work
that has been carried out by the motors. VFD’s are being controlled at the physical location,
where the drives were installed. The control of motor at the physical location makes time
consuming process and it increases the time for controlling the drives. To overcome this
drawback a wireless technology has been utilized in this proposed project to monitor and control
the speed of the motor. In this work an Internet of Thinks (IoT) is used to control the VFD. IoT
module enables the VFD into internet enabled and it can be interacted from remote location with
ease. The designed module can also be integrated with existing VFD and make it internet ready.
We can also monitor the speed of motor at any given time as it provides the real time data of
motor updated at an interval of each second. The speed performance of the motor is also
generated as a report by mobile application.

1] Introduction
Variable Frequency Drive (VFD) is also
called as Adjustable Frequency Drive , is widely
used in electro mechanical drive system to control
the torque and speed of the motor by varying the
frequency and voltage of the input. VFD’s are used
in various application in both small scale and large
scale industrial application.Most of the power
produced in the world are consumed by the electric
motors that are used in industries. The power can be
efficiently utilized by using the VFD’s. The
penetration of VFD’s are slow in the past decades as
the cost of power electronics devices that are used in

2. the manufacture of VFD’s are comparatively high. In
the Recent times as the cost of Power electronic
devices became cheap it resulted in the increased
usage of VFD’s.In all type of process and
manufacturing industries like sugar, steel, rubber,
cement, oil, gas, textile, chemicals and food
processing industries widely uses induction motor
for the specific applications. But for each and every
process the motor speed requirm
difficult to manufacture motor of different speed as it
won’t be economical, therefore the motors are
manufactured for some fixed speed of operation. The
speed of these kind of fixed speed motors can be
varied with the help many co
control methods of motor. The conventional speed
control method just varies the speed of the motor
only, but if the load of the motor increases it fails to
maintain the speed of the motor at some define
speed for the ongoing process.

existing VFD’s are controlled and adjusted in the
same physical location by analog or digital methods
in the place where the drives has been installed to
get the speed change of the motor depending on the
nature of theprocess.The schematic of VFD is shown
in Fig.1.
The proposed project work is to make the
VFD’s in to a non physical interventional system by
enabling the option of controlling the speed and also

devices became cheap it resulted in the increased

manufacturing industries like sugar, steel, rubber,
cement, oil, gas, textile, chemicals and food
processing industries widely uses induction motor
for the specific applications. But for each and every
process the motor speed requirments varies. It is
difficult to manufacture motor of different speed as it
won’t be economical, therefore the motors are
manufactured for some fixed speed of operation. The
speed of these kind of fixed speed motors can be
varied with the help many conventional speed
control methods of motor. The conventional speed
control method just varies the speed of the motor
only, but if the load of the motor increases it fails to
maintain the speed of the motor at some defined
speed for the ongoing process. This problem is
overcomed with the help of VFD’s.The current

4] Results And Discussion :
The speed of the motor can be varied by
varying the voltage input to the comparator, this
voltage variation is given by the wireless
microcontroller[7]. The TI CC3200 produces the
variable voltage starting from 0 to 3.3 Volts with the
voltage variation of 0.012 volts per step.
There are totally 256(2^8)steps as TI
CC3200 has a 8 bit DAC.The variable voltage thus
produced is given to the SCRdriver kit in order to
produce the speed change [4][5].The maximum
speed of the motor that has been used is 9000 RPM.
The speed of the motor with respect to different steps
is tabulated in the Table 1.

(a) Speed Monitoring:
The infra-red sensor is used to measure the
speed of the motor by calculation the pulse train. The
IR sensor consist of two pair of sensor one is
transmitter and another one is receiver. The
transmitter transmits the infrared waves and receiver
receives it. The encoder disc is allowed to or made to
rotate in between the two pairs. When the encoder
disc rotates the signal is hindered and receiver does
not receive signal until the gap in the receiver disc
comes. This creates a train of pulses with ON time
and OFF time.The real-time speed is continuously
monitored and it is logged in a cloud server BLYNK.
It also streams the live speed data of the motor in a
Android mobile application BLYNK.The speed is
shown as a function the time corresponding to the
moment of taking reading or monitoring.
(b)BLYNK:
BLYNK is a cloud platform and server
that is used to connect the TI CC3200 and Mobile
android app wirelessly with server integration.
(c) Speed control Mobile APP:
The speed is varied by dragging the slider
provided in the android mobile application [4][8] as
shown in Fig.6. By dragging the slider we can
produce the variable output ranging from 0 to 5 V.
This variable voltage to the comparator produces the
change in OP-AMP output.
Fig.6:Mobile application slider.
The Op-amp output is given to the Pulse
transformer, there it produces the PWM output.It is
then given to the SCR. The SCR depending the ON
and OFF time of the PWM output is provides
V/Fcontrol output it is then given to the motor.
Thereby we can achieve the speed control.
For different voltage that has been given to
the variable frequency drive we can observe different
duty cycle, revolution of the motor per minute.
These data had been tabulated in the Table.1 along
