Abstract

This paper describes the development of numerical model of human upper extremity able to perform movements and stabilization tasks in two degrees of freedom as a result of muscle activation controlled by a PID-based controller. These tasks are defined by functions of specified angle for every degree of freedom. Comparisons between model behaviour and experimental results show, that under certain conditions the model is able to perform reliable movements. But at the current stage of work, the level of muscle activation in fast movements can not be compared directly with the experimental values.
