(...)I am searching for information regarding the modeling of the human
standing posture as an inverted pendulum and, further, the
identification of the parameters of such a model using force plate data.
All answers will be summarized and posted. Thank you in advance (...)

I believe that Hemami, Koozekanani, and Barin
have done work in this area. They analyzed
stiffness matrices in feedback-control models.

This work is old, 24 years ago!, but it remains valuable. From seven
subjects who underwent several types of labyrinthian electrical
stimulations the author gives a model of 2nd order and its parameters.
You

thesis is the only complete publication.

I have been using an inverted pendulum model for modelling standing sway
in the sagittal plane (antero-posterior sway). The subject length and
mass together with force plate data (ground reaction force and centre
of pressure data) are used as input to the inverted pendulum model. The
output from the model is the pendulm's position of the center of mass in
the sagittal plane. A second order numerical differentiation gives the
acceleration. By comparing the model acceleration to the measured
acceleration, that is the ground reaction force devided with the body
mass, it is possible to analyse if the subject is behaving like an
inverted pendulum.
The model is described and validated in:

based and a marker based method.
