For the precision measurement and positioning, active anti-vibration apparatuses have been widely used. In order to improve the transmissibility of its apparatus, the control scheme that had the function of air spring stiffness canceling was previously proposed. In the proposed control loop, optimal triple parameters are in existence. In the industrial field, strict parameter tuning like optimal condition is hateful, because the specification of apparatus must be assured under the condition of parameter fluctuations. In this paper, using an orthogonal table L_<36> well-known in the quality engineering, a tolerance design method is proposed. Firstly, the control diagram of air spring type anti-vibration apparatus is shown. Next, the Linear Fractional Transformations is applied to its control block in order to express the parameter fluctuation. Furthermore, the table L_<36> is also introduced. Finally, based on the analysis of variance against L_<36>, it is shown that the parameter tolerance is decided.
