The paper presents an analysis of a mathematical model of the human arm dynamics in terms of observability. The purpose of the performed experiments is the selection of an observer for the possibility of arm tracking. The arm model is based on the two-link manipulator moving horizontally and vertically. For the study a model was linearized and the model part responsible for the work of human muscles...
In this paper, various concepts of controllability and observability of linear infinite-dimensional continuous-time control systems with constant coefficients have been studied. The paper contains a survey of various fundamental definitions, theorems and corollaries concerning approximate controllability, approximate boundary controllability and observability. Moreover, the different relations among...
