Abstract :
The research described in this paper integrates robust control design methodologies with flexible smart structures for achieving desired performance in the presence of uncertainties. The primary parameter uncertainty associated with smart structures is natural frequency variations. A control algorithm that incorporates the natural frequency variations and accommodates the available control effort is presented. The robustness properties are varified by implementing the proposed controller on smart structure test articles
