Active structural control using dymanic output feedback sliding mode

Abstract

This paper presents a dynamic output feedback control approach to active control of civil engineering structures. The design is based on sliding mode control, pole placement of the closed-loop eigenvalues, and linear functional observers for regeneration of the equivalent control and the sliding function from output measurements. A five-storey model used for testing the proposed control scheme is described. Simulation results demonstrate its validity. Future work on structural control issues using the approach is outlined.
