【Abstract】 Nowadays, in the fields of spaceflight & aviation and civil engineering, the environment combined centrifugal effect with vibration is brought greater importance. Some investigation is done abroad, while the research has just commenced in China. In this paper, the theoretical mathematical-model of the electro-hydraulic shaking table in the centrifugal force field is established, and the robust H ∞ control method is adopted. The rsult of simulation shows that this method is very useful for the system mentioned above.更多还原
