Author Affiliations +
In this paper a new method of distributed parameter control of flexible structures is considered. It is based on finite element approximation, from which the auto-regressive moving average representation of the distributed parameter system is derived. First, a discrete-time recursive least squares estimation algorithm is designed to estimate mass, stiffness and damping coefficient of the structure. It is then combined with a continuous time linear quadratic regulator algorithm, to form a hybrid distributed adaptive control system for the suppression of vibration in flexible structures. Simulation results are furnished to demonstrate the performance of the estimation algorithm and the adaptive controller.
