Content:
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.
