Recently, high-resolution measurement instruments such as probe microscopes have been used widely, since their price is getting lower, and their size is becoming smaller. Therefore, these measurement instruments have been used in various environments. However, to use these instruments effectively, it is important to isolate the environmental vibration transmitted to the instruments. For this reason, we are developing new built-in type multi-axis vibration isolation devices equipped with inertia force generators (IFG). In designing this vibration isolation device, modal analysis and "direct inertia force control (DIFC)" are used. DIFC is the newly developed design method for the vibration control systems proposed by authors. Combination of modal analysis and DIFC can make the complex control system design process simple and clear. In this paper, we show how the controller is designed, and also discuss the effectiveness of the method by experiment.
