An Approach to Control of Human Leg Switched Dynamics

Abstract

This article describes the approach to control of human leg dynamical model as a switched linear system. The control scheme consists of fractional and integral order PID controllers. In the paper we analyze the responses of the system depending on the above-mentioned controllers. We focus our attention on angular displacements only. The angular velocity maybe arbitrary. Additionally, we present the method how to design a human leg as the switched linear system. In this case the switching rule is state-dependent. Finally, we present two illustrative examples for two different trajectories.
