Acceleration based smart structure (MEMS) control design for aerospace applications

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 state estimate based feedback using various measurements related to motion variables such as accelerations, velocities and displacements. Controller designs are based on equivalent first-order state-space baseline design gains that use existing algorithms. The proposed method provides different norms for estimator and controller gains, thereby allowing more flexibility in gain magnitudes and selection of sensors
