      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 ...

      Robustness and Performance of Adaptive Suppression of Unknown Periodic Disturbances 

      Jafari, S.; Ioannou, Petros A.; Fitzpatrick, B.; Wang, Y. (2015)
      In recent years, a class of adaptive schemes has been developed for suppressing periodic disturbance signals with unknown frequencies, phases, and amplitudes. The stability and robustness of these schemes with respect to ...
