Characteristic Variable Based Robust Design for Dynamic System

Abstract

In this paper, a dynamic robust design method is proposed to achieve a desirable dynamic performance in despite of parameter variation. Since it transforms the robustness of a dynamic system into the robustness of its characteristic variables, the complex dynamic robust design problem becomes a relatively simple static robust design problem. This greatly eases complex of this design. The effectiveness of the proposed method is further demonstrated by a comparison with the existing method on design of a practical hydraulic press machine.
