My association with the theory of controls in continuous time started during my studies at
the Indian Institute of Technology, Kharagpur, India, in 1974 as an undergraduate student
in the Controls and Power program. The initial introduction by Professors Kesavamurthy,
Y. P. Singh, and Rajagopalan laid the foundation for a good basic understanding of the
subject matter. This pursuit and further advanced study in the field of digital controls
continued during my days as a graduate student in the Electrical and Systems Engineering
Department at the University of Connecticut in Storrs, from 1983 to 1988.
