In this paper, we discuss regarding simulation and experiment results of isolated vibration characteristics by LQG and I-LQG feed back, besides nonlinear characteristics of a repulsion form magnetic levitation system using two permanent magnets are shown by experiments. Although both LQG and I-LQG are designed conventionally by using a linearized model for control, we also show that the nonlinear phenomenon. By this reason, we consider that the affinity is good fairly to use the isolated vibration characteristic by both LQG and I-LQG inside the saturation range, to the repulsion form magnetic levitation system using two permanent magnets. It is the other reason that we confirmed the isolated frequency characteristic of isolation table from vibration disturbance with the gain jump phenomenon to be held. It will be a future problem to reduce the steady state deviation due to hysteresis property in the case of direct disturbance.
