Book Description
The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology impacts all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computing methods, applications, philosophies, . . . , new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. The autotune method of Astrom and Hagglund had a major impact on the hardware and structure of PID process controllers. However, despite a substantial body of theoretical analysis, progress in transferring the benefits of more general self-tuning methods to industrial devices and processes has been much slower. This volume by Dr's Stephan and Keuchel shows that this type of technology transfer can be achieved and that the more advanced adaptive controllers do give performance benefits over conventional industrial (three term) controllers. The volume also shows the requirements in hardware, the need for software skills and the engineering techniques required to achieve satisfactory results. We hope that by recording their engineering know-how more researchers and industrialists will be encouraged to tap the benefits of advanced self-tuning and adaptive control methods.

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
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.
