Abstract
The measuring device we developed to evaluate the leg and use in physical training is driven by a linear motor using impedance or proportional-integral control. The leg is considered a second-order system in the short range. For a leg flexed at a constant speed, we calculated parameters from measured force, displacement, and acceleration and measured parameter transitions in exercise. While the damping coefficient remained almost flat during exercise, the spring constant changed.
