Control of Machines is one of the most important functional areas for electrical and mechanical engineers working in industry. In this era of automation and control, every engineer has to acquaint himself on the design installation, and maintenance of control systems. This subject must find its place as a compulsory applied engineering subject in degree and diploma curriculum.Some progressive states and autonomous institutions have already introduced this subject in their curriculum. In this book, static control and programmable controllers have been included keeping in view the latest developments in modern industry. Relay and static control have been dealt with in details. Most of the control circuits included in this book have been taken from Indian industry. A chapter has been devoted to protection of motors and troubleshooting in control circuits.The chapter on PLC has been made very elaborate to deal with all aspects of logic controllers. Review questions have been included at the end of each chapter. The explanations of circuits and design procedure of control circuits have been made very simple to help students understand easily. Students, teachers and shop floor and design office engineers will find this book a very useful companion.

It is my ambition in writing this book to bring tribology to the study of control of machines with friction. Tribology, from the greek for study of rubbing, is the discipline that concerns itself with friction, wear and lubrication. Tribology spans a great range of disciplines, from surface physics to lubrication chemistry and engineering, and comprises investigators in diverse specialities. The English language tribology literature now grows at a rate of some 700 articles per year. But for all of this activity, in the three years that I have been concerned with the control of machines with friction, I have but once met a fellow controls engineer who was aware that the field existed, this including many who were concerned with friction. In this vein I must confess that, before undertaking these investigations, I too was unaware that an active discipline of friction existed. The experience stands out as a mark of the specialization of our time. Within tribology, experimental and theoretical understanding of friction in lubricated machines is well developed. The controls engineer's interest is in dynamics, which is not the central interest of the tribologist. The tribologist is more often concerned with wear, with respect to which there has been enormous progress - witness the many mechanisms which we buy today that are lubricated once only, and that at the factory. Though a secondary interest, frictional dynamics are note forgotten by tribology.

Basic models and concepts of machine dynamics and motion control are presented in the order of the principal steps of machine design. The machine is treated as a coupled dynamical system, including drive, mechanisms and controller, to reveal its behavior at different regimes through the interaction of its units under dynamic and processing loads. The main dynamic effects in machines are explained. The influence of component compliances on accuracy, stability and efficiency of the machines is analyzed. Methods for decreasing internal and external vibration activity of machines are described. The dynamic features of digital control are considered. Special attention is given to machines with intense dynamic behavior: resonant and hand-held percussion ones. Targeted to engineers as well as to lecturers and advanced students.
