Abstract :
In this paper, a robust control profile is generated which suppresses all the high frequency resonant dynamics in a flexible dynamic system. This robust control profile is the shifted time-limited version of the functions that optimally achieve the time-frequency localization. The robust control profile is optimized by considering the first resonance mode through the filter theory. The simulation results for hard disk drive seek control show the effectiveness of the proposed method.
