Active shape control of a flexible structure consists of estimating the deformed shape from multipoint spatially distributed measurement of the structural deflections and restoring the desired shape actively by means of electromechanical or piezoelectric control actuators. We present a method of determining the structural deflections accurately and of designing the optimal control forces to restore the desired shape. The estimation algorithm is based on an infinite-dimensional approach, where the necessary finite-element truncation and approximation are introduced after solving the estimation problem. Using the same approximation functions the proposed method yields the optimal control forces that minimize the overall restoration error in the sense of least squares. We apply the proposed shape estimation and control method to an experimental tendon control system for a flexible beam and study the optimum moment-arm location.
