Abstract
A method is presented for estimating the time-varying compliance param eters of the elbow joint from a single movement. The method separates by frequency the perturbed from the voluntary response, then determine s the parameters by exponentially weighted least squares. The tracking performance of the method is established by simulation and by a calib rated mechanical joint. Experimental results are presented on time-var ying posture and slow movement.
