Book Description
A microprocessor based DC motor speed control system is presented, incorporating digital proportional and integral control schemes in the system software. A variable duty cycle SCE/dicde bridge is used to provide the DC controlling voltage for the DC motor aramture. PPM feedback is provided by a shaft mounted slotted disc and an optical interrupter circuit. A, current to voltage transducer and an A/D converter circuit allow software monitoring of the armature current; providing instantaneous and I z t current limiting. A keyboard monitor system permits the modification of motor control constants and set points; as well as allowing the user to enter and execute assembly language programs. Binary floating point addition, subtraction, multiplication, and division routines are included in the system software package. These routines are used in the implementation of the motor control software, as well as allowing the microprocessor system to be used as a four function calculator. Floating point decimal to binary and binary to decimal conversion routines are included to permit interfacing between the system and its human operator. This work discusses the digital control algorithms used, and illustrates the motor's response to step load changes and BPM setpoint changes with various combinations of control parameters. The hardware and software of which the system is composed is also discussed.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Book Description
Microcomputer Design and Applications provides information pertinent to the fundamental aspects of microcomputer design and applications. This book presents a design approach for multiple-processor computers. Organized into two parts encompassing 16 chapters, this book begins with an overview of a number system and supporting computational algorithms, which is especially useful for microcomputer control and digital signal processing. This text then presents an integrated technical and management-based method for developing microprocessor software. Other chapters consider file structures for a small-scale database system designed for microprocessor implementation and present the formulation of file structures for a typical microprocessor/flopping disk system. This book discusses as well the proposed solution to specify a high-level, machine-oriented, structured programming language suitable for general microprocessors and to implement a portable compiler for this language. The final chapter deals with a distributed processing system for non-invasive cardiac surveillance. This book is a valuable resource for engineers and computer scientists.

Book Description
Microprocessors: Principles and Applications deals with the principles and applications of microprocessors and covers topics ranging from computer architecture and programmed machines to microprocessor programming, support systems and software, and system design. A number of microprocessor applications are considered, including data processing, process control, and telephone switching. This book is comprised of 10 chapters and begins with a historical overview of computers and computing, followed by a discussion on computer architecture and programmed machines, paying particular attention to the functions of a computer such as the representation and processing of numbers, symbols, and characters. Subsequent chapters explain how a microprocessor works and outlines the basics of microprogramming, along with types of input and output, system design, and microprocessor selection. The use of ROMs to replace combinational logic is considered. Finally, the use of microprocessors in management is discussed. A glossary of terms used throughout the text is included. This monograph will be of interest to computer scientists, computer programmers, systems designers, electronics engineers, undergraduates, and microprocessor enthusiasts.

Book Description
Real Time Digital Control Applications is a compilation of papers presented at the Symposium on Real-Time Digital Control Applications, sponsored by the International Federation of Automatic Control (IFAC) and the International Federation for Information Processing (IFIP), held in Guadalajara, Mexico. The event is organized to provide developing countries with the opportunity to gain insights -- from the sharing of ideas and experiences of experts from around the world to the rapid growth and development of applications of real-time digital control systems, which is considered as the basis of industrial revolution. The book presents and discusses the various scientific, industrial, and technical applications of real-time digital control systems. Applications in power generation, water, metal processing, cement, food, and manufacturing industries are shown. The text also covers applications in robotics, biomedicine, monitoring and failure detection, fuel optimization and heat control, adaptive process control, modeling, and computer software. Industrial engineers, scientists, economists, computer scientists, robotics experts, planners, and technicians will find this book invaluable.

Book Description
Recent advances in LSI technology and the consequent availability of inexpensive but powerful microprocessors have already affected the process control industry in a significant manner. Microprocessors are being increasingly utilized for improving the performance of control systems and making them more sophisticated as well as reliable. Many concepts of adaptive and learning control theory which were considered impractical only 20 years ago are now being implemented. With these developments there has been a steady growth in hardware and software tools to support the microprocessor in its complex tasks. With the current trend of using several microprocessors for performing the complex tasks in a modern control system, a great deal of emphasis is being given to the topic of the transfer and sharing of information between them. Thus the subject of local area networking in the industrial environment has become assumed great importance. The object of this book is to present both hardware and software concepts that are important in the development of microprocessor-based control systems. An attempt has been made to obtain a balance between theory and practice, with emphasis on practical applications. It should be useful for both practicing engineers and students who are interested in learning the practical details of the implementation of microprocessor-based control systems. As some of the related material has been published in the earlier volumes of this series, duplication has been avoided as far as possible.
