Design of Structural Active Control with Disturbance Attenuation

Abstract

This paper proposes a design method of the active control with disturbance attenuation in some structural systems. Its aim is to design a robust state feedback controller via eigenstructure assingment. Based on a result of parametric eigenstructure assignment, this problem is changed into an optimal problem with some constraints and the corresponding algorithm is proposed. This method utilizes directly the original matrices in the structure systems, thus it is convenient to use in applications. A three-story shearing type model under earthquake excitation is analyzed by using the proposed algorithm and the simulation results show the effectiveness of this proposed algorithm.
