Abstract

Based on the four-block formulation of the active deformation suppression problem, the concepts of actual and optimistic lower limits of deformation suppression in terms of the H^∞ norm have been introduced for flexible structures for limited numbers of actuators and sensors. These limits have been used to construct a hybrid search algorithm for actuator and sensor mapping optimization, resulting in significant gains in computational costs. A simply supported beam control has been used as a numerical testbed, to demonstrate the acclaimed properties of the lower limits of deformation suppression
