Abstract

The objective in this paper is to combine the finite element method with the robust control design method. The finite element method results in a high-complexity model with a large number of degrees-of-freedom, which is the basis of the control design. The superposition method, is applied as a modal reduction in order to reduce the large-scale finite element model into an acceptable reduced-complexity model. This method guarantees the effective selection of all the significant frequencies in the control design sense. In the design of a robust control both the performance specification and the model uncertainties are taken into consideration. To demonstrate the effectiveness of the proposed procedure a finite element structure of a bus model with 3444 degrees-of-freedom is applied. The active suspension system designed is tested with the original non-linear finite element model.
