am not an engineering that why am looking for simple clear equations to calculate COM from force plate..
Dear Dr. Ehab,
I hope you in a good health, from the force you can get acceleration (a=F/m), and you can calculate the displacement by double integration of acceleration.
I hope this answer help you.

Thanks Dear Dr Abdel-Rahman.
the issue in the double integration calculation... as you see in the attachment, I ve problem in last 2 equations for double integration
Dear Dr. Ehab,
I think this is the easier way to calculate the displacement from force. So, you can use any data analysis software to do integration such as OriginPro or any motion analysis software (available).
This task can be quite complex. For example, you analyze the movement of a standing person. His model is an inverted pendulum. Its uncontrolled motion is unstable and measurement errors entail large errors in the calculation of the coordinates of the center of mass. It is necessary to adjust the result.

PS. Algorithms of this article work well at zero mean value of the signal for short records. The error equation for these estimates is unstable, and the error can accumulate. Algorithms of this article work well at zero mean value of the signal for short records. The error equation for these estimates is unstable, the error can accumulate. Algorithms can be improved if the time intervals on which the person stands quietly are known. My student did this in his thesis, but the results have not been published even in Russian.
