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.

Arm cortex ( lpc 2148 ) based motor speed control Uday 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.

Bi directional speed control of dc motor and stepper motor through mat lab us...eSAT Journals
Abstract In any industry speed control of an electric drive system is very critical and crucial. Every designer aims at achieving a control methodology having high degree of precision. But industry needs are ever evolving in nature. Hence it is very much essential that along with conventional speed control mechanisms we must also have simple interactive graphical based control strategies. Several algorithms/methodologies have been developed over the years to achieve speed control of motors. In this context by encompassing the usability of Mat Lab, work has been done to control the speed of stepper motor and DC motor using microcontroller. Microcontroller is programmed to achieve bi directional speed control. The main objective of this work is to develop the graphical user interface of motor control through mat Lab guide and the interface of the same with hardware via serial communication. PIC is used as the controller. Keywords— DC, PIC, μC, AC, GUI, IC
Mainly the DC motors are employed in most of the application. The main objective is to Regulate the DC motor system. A motor which displays the appearances of a DC motor but there is no commutator and brushes is called as brushless DC motor. These motors are widespread to their compensations than other motors in relationships of dependability, sound, efficiency, preliminary torque and longevity. To achieve the operation more reliable and less noisy, brushless dc motors are employed. In the proposed work, dissimilar methods of speed control are analysed. In real time submission of speed control of BLDC motor, numerous strategies are executed for the speed control singularity. The modified approaches are the employment of PI controller, use of PID controller and proposed current controller.

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 pulse applied to it (popularly known as PWM control).

A motor driver IC is interfaced to the STM32 board for receiving PWM signals and delivering desired output for speed control of a small DC motor. Further the project can be enhanced by using power electronic devices such as IGBTs to achieve speed control higher capacity industrial motors.

ABSTRACT
Role of electrical drives is a major concern in industrial automation. Dc motors feature a speed, which can be
controlled smoothly down to zero, immediately followed by acceleration in the opposite direction without power
circuit switching and Dc motors respond quickly to changes in control signals due to the dc motor's high ratio of
torque to inertia. Thus, here the system is design to control the speed of the motor which provides RS232
interface which is a standard for both PC and PLC. A set of commands is used to control drive
Keywords - Dc motor, Microcontroller, RS232, Thyristor
I. INTRODUCTION
In this system various commands are given
to drive by a computer RS232 interface. The drive
responds accordingly like start, stop, and variable
speed. The system supports UART protocol, fixed
baud rate (9600bps). Field sense and current sense
circuits are for protection of drive. The PC available
to control operation of speed of motor which can
increase productively wide range of industry RS232
signal transmitter end and receiver which transmit
information according to signal relative to data size
Process control and energy conservation are the two
primary reasons for using an adjustable speed drive.
Historically, adjustable speed drives were developed
for process control, but energy conservation has
emerged as an equally important objective. SCADE
type systems often require controlling devices from
PC directly. PLC demands PROFIBUS support in
drives for interfacing. But PC does not have
PROFIBUS. Thus only one drive cannot be used
with both technologies. In this project this system is
used to control the DC motor up to 3 HP also result
in high power consumption motor run smoothly but
this drive is fully digital firing is done by
microcontroller and on analog port potentiometer is
connected this system is divided into three parts as
firing circuit armature circuit, field power section
firing circuit. this section is main heart of the project
this control the firing pulses of the phase following
the control pulse transformer which convert the
firing pulses square wave in a pulse of fine edge is
fed to the gate of SCR it is fired rapidly because fine
edge contain more current it is drive by transistor
which provide sufficient current gain to the pulses
this is used because microcontroller runs at low

II. HARDWARE SCHEME:
In this project Driver circuit is designed to
interface microntroller with PC generator firing
pulses project based on dual converter thyristor
based design (H Bridge). Firing is done by
microcontroller which trigger the thyristor and speed
of DC motor is controlled, A step down transformer
is used to convert 230v AC to 12v/5A and it will
send to bridge rectifier. This rectifier convert AC
output from transformer into DC output by voltage
regulator 7805,7912(12v/5A). Voltage output which
is obtained is DC and it is given to microcontroller.
Field supply is also given which is check by
mirocontroller. when drive is ON, the four thyristor
of Dual converter (H Bridge) is in forward direction.
Current flows through resistance and diode
connected which limit the current and voltage sense
by protecting device OPAMP. Dual comparator

Fig.1 block diagram of the system
Detector circuit is used in upper and lower
half of sine wave this OPAMP will sense the high
current and voltage if output is high. It will read by
microcontroller with logic 1 other OPAMP LM741
is also use to sense high voltage if output is high
similarly if output obtained by LM741 is low it will
read by microcontroller with logic 0.Eight opto
coupler PC817 which are connected to
microcontroller pins which is used to isolate
between controller and power circuit. It is used to
convert AC wave to square wave of 5V and sine
wave coming from synchronizing transformer. It is
in the form of current and voltage signal received by
optocoupler then these signals are read by
microcontroller logic 1 and logic 0 to generate the
firing pulses microcontroller. Timer 0 and timer 1
are used to decide the time of pulse firing at 0.1 sec.
Four pulse transformer 1:1:1 (430v/5A) is used
which convert firing pulse of square wave coming
from microcontroller into sine wave of fine edge is
fed to SCR. It is fired since it contains more current.
Driver TIP122 Darlington transistor (12v/5A)
provides sufficient current to pulse transformer.
Microcontroller gives firing pulses of low current
