Research Interests and Professional Activities
Primary research interests- Various aspects of multivariable control theory and applications to advanced spacecraft and aircraft. Some past research contributions include: novel decoupled fine-pointing control laws for space-based systems that require sub-arc-second accuracy; fundamental robust control theory for flexible space structures; globally stable closed-loop maneuvering and attitude control laws for nonlinear multibody flexible spacecraft and manipulators; and energy-extracting active control methods for noise reduction. Served as a key technical leader in the Control-Structure Interaction(CSI) program, which incorporated the concepts and results to produce a new methodology for integrated design of spacecraft that are optimal with respect to structural design as well as control system design.

Recent and current research- Control of systems under dynamics uncertainties, anomaly, and failures, with applications to aircraft. In particular, co-developed new direct adaptive control schemes that enable stable control in spite of anomaly such as unknown actuator failures (e.g., stuck control surfaces, hydraulics failures, engine failure), icing, and structural damage, occurring at unknown instants of time.

Publications- Over 210 technical publications including 3 books and 5 book chapters.

Professional Activities- Served in many active leadership roles in the IEEE, AIAA, and ASME; several editorial boards (journals and conferences), governing boards, technical- and program- committees, panels, and steering committees. As an amateur cartooninst, regularly contributed of the Out of Control technical cartoons in the IEEE Control Systems Magazine (1985-94). Non-controls technical interests include Digital signal processing (incl image and speech Processing); Digital communications; Satellite, wireless, and cellular communications; Pattern recognition; Robotics; Active control of noise; and Cross-discipline applications of system theory.
