Petersen, Ian Richard, 1956-

Ian Richard Petersen (born 1956) is an Australian control theorist known for his contributions to robust control, quantum control, and stochastic systems. He has worked on the theoretical foundations of quantum feedback, risk-sensitive and H-infinity control, as well as frameworks for the analysis of negative imaginary systems. He is particularly known for his work in H-infinity control, and is regarded as one of the pioneers in the field of quantum control theory. He is a professor at the Australian National University (ANU), affiliated with the Research School of Engineering. Petersen is one of the researchers who introduced the concept of negative imaginary systems, providing a theoretical foundation for their analysis and control.
