This study expresses a novel active vibration control method for a house structure by using magnetic levitation. The magnetic levitation system is easy to install to the ceiling because there is no need to use linear guides or bearings. In this study, a magnetic levitation device is attached to the iron plate fixed firmly to ceiling of the structure and it will levitate when a vibration occurs. The total mass of structure will be decreased while levitating, resulting in the change of its natural frequency. Moreover, an efficient vibration control method is examined. Finally the results of experiments are shown to confirm its feasibility.

In this study, we conduct experiments of human balancing task and present a stochastic dynamic model of the human balancing task. The parameters of the stochastic dynamic model are identified using particle swarm optimizers. Tn order to examine stochastic behavior of the human balancing, we experimentally estimate probability density function of the state quantities. The experimental result implies that the behavior of the human balance seems to be fat-tailed distribution. This experimental observation was reproduced by the model that has additive and multiplicative white Gaussian noise. This work has implications for designing human-like motions of artificial agents such as human-like partner robots.
