Abstract

In this paper, a design approach for controlling a composite plate structure subject to aeroelastic loading using piezoelectric actuators and sensors is presented. The nature of the sensing variables is exploited and accommodated in the control design algorithm. The controller is a feedback controller that uses various measurements related to motion variables such as accelerations, velocities and displacements. Proposed controller designs in this paper are based on equivalent first order state-space baseline design gains that use existing control system design software. The proposed method provides different norms for controller gains, thereby allowing more flexibility in gain magnitudes and selection of sensors and still meet the time response specifications.
