Relay Tuning of PID Controllers

M. Chidambaram is currently a Professor at the Department of Chemical Engineering, Indian Institute of Technology in Madras, Chennai. After completing his PhD at the Indian Institute of Science in Bangalore he served as a faculty member at the Indian Institute of Technology Bombay, Mumbai, from 1984 to 1991. Since then he has been a faculty member at the Indian Institute of Technology in Madras. He has also served the institute as Head of the Department of Chemical Engineering from 2000 to 2003 and as the Director, National Institute of Technology (NIT), Tiruchirappalli from 2005 to 2010. He has 190 journal articles, 7 books and 4 book chapters to his credit. His primary research interest is in the area of process control. 'Nikita Saxena completed her PhD' under the guidance of Prof. M Chidambaram. She completed her degree (BTech) in Chemical Technology at Harcourt Butler Technical Institute (HBTI), Kanpur. She also has a year of experience in the fast-moving consumer goods (FMCG) industry. She has authored 4 journal articles and presented papers at several conferences. Her areas of interest include relay control systems and model identification.
