Abstract

This work develops a simple low order model of the lower leg that incorporates the effects of a nonlinear biceps femoris muscle actuator and explores the feasibility of identifying a nonparametric model for the knee joint’s rotational behavior as well as the joint activation function that drives the motion. The NL-LTP algorithm is applied to this system and some promising results are obtained. In particular, the nonlinear equations of motion and the joint activation moment are estimated from the “measured responses”. The accuracy of these nonlinear parameter estimates and the implications for future experimental studies of biomechanical systems are discussed.
