The speed control of DC motors is crucial especially in applications where precisions and protection are of importance. This work investigates and implements a microcontroller-based adjustable speed drive system for a system shunt motor. The theory of the armature voltage control algorithms in a closed loop system has been successfully implemented. An IGBT switch is used in buck configuration to control armature voltage of the motor. The PWM signal that controls the IGBT is generated from a motorola 68 HC11 microcontroller. The speed of the motor is measured by a shaft encoder and directly fed to the microcontroller along with a speed reference signal. A data acquisition routine reads the measured speed and the reference speed in digital format and generates the error value signal. The error values signal is directly fed into the proportional controller routine to commute the controller output. Finally, the controller output is used to generate a PWM, which completes the loop by controlling the switch. To protect the motor from gih current, a current monitoring routine is implemented to read the motor current through a Hall effect sensor. If the motor current is higher than its rated curent halting the PWM generation routine will stop. Experimental results obtained have supported the idea of the design. The speed of the motor could be controlled over a wide range using the dc chopper and the PWM. Employment of a microcontroller has shown a great improvement in the acceleration, speed reduction, and deceleration and over current protection of a dc motor.

Mixed-Signal Embedded Microcontrollers are commonly used in integrating analog components needed to control non-digital electronic systems. They are used in automatically controlled devices and products, such as automobile engine control systems, wireless remote controllers, office machines, home appliances, power tools, and toys. Microcontrollers make it economical to digitally control even more devices and processes by reducing the size and cost, compared to a design that uses a separate microprocessor, memory, and input/output devices. In many undergraduate and post-graduate courses, teaching of mixed-signal microcontrollers and their use for project work has become compulsory. Students face a lot of difficulties when they have to interface a microcontroller with the electronics they deal with. This book addresses some issues of interfacing the microcontrollers and describes some project implementations with the Silicon Lab C8051F020 mixed–signal microcontroller. The intended readers are college and university students specializing in electronics, computer systems engineering, electrical and electronics engineering; researchers involved with electronics based system, practitioners, technicians and in general anybody interested in microcontrollers based projects.

In this book the four quadrant speed control system for DC motor has been studied and constructed. To achieve speed control, an electronic technique called pulse width modulation is used which generates high and low pulses. These pulses vary in the speed of the engine. For the generation of these pulses, a microcontroller is used. It is a periodic change in the program. Different speed grades and the direction are depended on different buttons. The experiment has proved that this system is higher performance. Speed control of a machine is the most vital and important part of any industrial organization. This paper is designed to develop a four-quad speed control system for a DC motor using microcontroller. The engine is operated in four quadrants ie clockwise, counterclockwise, forward brake and reverse brake. It also has a feature of speed control. The four-quadrant operation of the dc engine is best suited for industries where engines are used and as a requirement they can rotate in clockwise, counter-clockwise and thus apply brakes immediately in both the directions. In the case of a specific operation in an industrial environment, the engine needs to be stopped immediately. In this scenario, this system is very integral. The PWM pulses generated by the microcontroller are instantaneous in both directions and as a result of applying the PWM pulses. 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 engine through a motor driver IC. The speed and direction of DC motor has been observed on digital CRO

Direct current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the DC motors will ensure that it is widely used in many applications. This project is mainly concerned on DC motor speed control system by using microcontroller PIC 16F877A. Pulse Width Modulation (PWM) technique is used where its signal is generated in microcontroller. The program for PWM generation is written in C+ Language using MPLAB IDE software. It is programmed into the microcontroller using PIC Microcontroller Start-up Kit. Then the microcontroller is installed into the motor control circuit. The Microcontroller acts as the motor speed controller in this project. The PWM signal will send to motor driver to vary the voltage supply to motor to acquire desired speed. Besides, it also shows a graph of motor speed versus PWM dutycycle percentage to let the user monitor the performance of the system easily. Based on the result, the readings are quite reliable. Through the project, it can be concluded that microcontroller PIC 16F877A can control motor speed at desired speed efficiently by using Pulse Width Modulation signal.

Welcome to Basics of Microprocessors and Microcontrollers! This is a nonfiction science book which contains various topics on basics of microprocessors and microcontrollers. A microprocessor is a type of computer processor where the logic and control for data processing are housed on a single integrated circuit or a few interconnected integrated circuits. The arithmetic, logic, and control circuitry needed to carry out the tasks of a computer's central processing unit are all included within the microprocessor. The integrated circuit has the ability to understand, carry out, and perform arithmetic operations. The microprocessor is a multifunctional, clock-driven, register-based, digital integrated circuit. It receives binary data as input, processes it in accordance with instructions stored in its memory, and outputs the results (also in binary form). Combinational and sequential digital logic are both present in microprocessors, which use the binary number system to represent numbers and symbols. On the other hand, A microcontroller, commonly known as an MCU (microcontroller unit), is a tiny computer that is housed on a single VLSI integrated circuit (IC) chip. One or more CPUs (processor cores), memory, and programmable input/output peripherals are all included in a microcontroller. Along with a tiny amount of RAM, on-chip program memory frequently also includes ferroelectric RAM, NOR flash, or OTP ROM. In contrast to the microprocessors used in personal computers or other general-purpose applications made up of numerous discrete chips, microcontrollers are intended for embedded applications. Automotive engine control systems, implantable medical devices, remote controls, office equipment, appliances, power tools, toys, and other embedded systems are just a few examples of the automatically controlled products and devices that use microcontrollers. This is the first edition of the book. Thanks for reading the book.

The DC motor uses in drive system in many industrial applications are still significant. In this project, the DC motor controlled based on microcontroller PIC 18F4550 is proposed. The controller will control the speed and direction of the DC motor. The microcontroller will generate the PWM (Pulse Width Modulation) signal and use to control the speed of motor. The DC drive will be used to control the direction of the DC Motor. The analysis of the drive performance is also carry out in this project. The experiment showed that the motor speed can be controlled via microcontroller from zero to maximum speed easily at low cost since PIC has built in programmable timers, ports and interruption where no extra hardware is needed.
