This study is aimed for the construction of balance model of human body during standing on frontal plane. Generally, it is difficult to build the balance model because the sensory feedback system of human body is unknown. Therefore we suggest a stable balance model describing result from frequency response test. In the test, phase delay occurred in low frequency range less than 0.2 Hz. We hypothesized that this delay generated by velocity feedback of support surface through visual sensing. Based on this hypothesis, we built a model and estimated feedback parameters using least square method. Then a reasonable and stable model describing the peculiarity of frequency response diagram in low frequency range was obtained. To verify the validity of the identified parameters, we confirmed that the delay time almost accorded with the typical time.
