Discrete Riccati modeling of patellar-tendon-reflexes

The present paper proposes the use of a discrete Riccati model for characterizing patellar-tendon-reflexes (PTR) from data obtained with uneven force increments. Two modified parameter identification methods are used and compared with the previous algorithm to show the veracity of the proposed methods. The form of proposed model is based on the exact discretization method, which converges to an underlying continuous model as the force increments approach zero. Such a model is useful in deepening the understanding of PTR motions as well as simulating PTR motions under digital control.
