Digital Control Kannan M. Moudga

Digital control is a branch of control engineering that deals with the design and implementation of controllers using digital systems, such as microprocessors, digital signal processors, and computers. Digital control has many advantages over analog control, such as higher accuracy, flexibility, reliability, and cost-effectiveness. Digital control also enables the use of advanced control techniques, such as optimal, adaptive, and robust control, that are difficult or impossible to implement using analog devices.

One of the leading experts in the field of digital control is Professor Kannan M. Moudgalya, who is an associate dean at the Indian Institute of Technology (IIT) Bombay. Professor Moudgalya has written a comprehensive textbook on digital control, titled Digital Control, which was published by John Wiley & Sons in 2007. The book covers the fundamentals of digital control, as well as various topics such as digital signal processing, plant identification, PID control, pole placement, internal model, minimum variance, model predictive, and linear quadratic Gaussian control. The book also provides numerous examples, problems, solutions, and MATLAB code to illustrate the concepts and applications of digital control.

The book is organized into five sections: Section 1 introduces the basics of linear systems and modelling of sampled data systems; Section 2 discusses digital signal processing and plant identification from measurements; Section 3 presents the transfer function approach to control design; Section 4 explains the state space techniques for control design; and Section 5 explores some extensions and applications of digital control. The book is suitable for senior undergraduate and postgraduate students in chemical, electrical, mechanical engineering, and computer science, as well as practicing systems engineers who want to learn digital control.

Professor Moudgalya has also made his book available online for free, as well as his MATLAB code, which can be downloaded from his website. He has also created a series of video lectures on digital control, which can be accessed from the National Programme on Technology Enhanced Learning (NPTEL) website. Professor Moudgalya is an active researcher and teacher in the areas of digital control, process systems engineering, open source software, and education technology. He has received several awards and honors for his contributions to engineering education and research.

Digital control is a rapidly evolving and important field in the modern world. It has applications in various domains such as aerospace, robotics, manufacturing, power systems, biomedical engineering, and more. By learning digital control from Professor Moudgalya's book and lectures, one can gain a solid foundation and a competitive edge in this exciting field.
