IMPLEMENTATION OF ROBUST CONTROL THEORY IN SMART STRUCTURE DESIGN USING FREQUENCY DOMAIN DATA

Abstract eng:
Τhis paper presents an implementation of a design method of robust H∞ optimal control to a structural control system. To obtain the best possible performance in the face of uncertainties, robust H∞ optimal control for the active control structure is used. Relevant numerical techniques, which have been implemented with the help of MATLAB routines, are applied to solve the formulated structural control problem. By proper selection of the weight factor, the seismic response of the building structure can be reduced considerably. Numerical results show high robust performance of the proposed method.
