Areas Of Expertise
Dr. Steven Hall received the S.B. (1980), S.M. (1982) and Sc.D. (1985) from MIT, all in aeronautics and astronautics. He joined the MIT faculty in 1985 as an assistant professor, was promoted to associate professor in 1991 and awarded tenure in 1994. He was a visiting professor at the University of Michigan from 1992-93. Dr. Hall is currently the Raymond L. Bisplinghoff Faculty Fellow in Aeronautics and Astronautics, a fellowship he has used to study active learning techniques and introduce those techniques into the department curriculum. His research is in aerospace systems control theory and practice, mainly the control of flexible structures such as space structures, and helicopter rotor dynamics. He has made a pioneering contribution to the control of helicopter rotors through the development of new piezoelectric actuators. These actuators, mounted inside each helicopter blade, drive a small flap that changes the lift on each blade up to 100 times each second to counter vibration. This has led to the first successful demonstration of vibration control using blade-mounted actuation, on a model rotor at MIT. Professor Hall's main research interests are the control of flexible structures, especially space structures; and control of helicopter rotor dynamics, especially using piezoelectric actuators. In the flexible structure control area, the main focus is the development of methods for designing high performance controllers which are robust to model uncertainty. In the rotor control area, the emphasis is on the development of blade-mounted actuators for high-frequency control of vibration, noise, etc.
