      Adaptive notch filter using real-time parameter estimation 

      Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A. (2011)
      The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation ...

      Robust stability and performance of adaptive jitter supression in laser beam pointing 

      Jafari, S.; Ioannou, Petros A.; Fitzpatrick, B.; Wang, Y. (Institute of Electrical and Electronics Engineers Inc., 2013)
      This paper studies the robustness and performance of an adaptive scheme for suppression of laser beam jitter in the presence of unmodeled dynamics in a continuoustime formulation. To demonstrate the level of performance ...
