State Feedback Controller Based on Bond Graph Observers

Vol. 18  No. 4  pp. 116-125


This paper presents a comparative study between two techniques in order to outline the stability performances of the string tension racket of stringing machine, when we apply the state feedback controller. These two techniques are the graphic approach which based on Bond Graph (BG) tool, and the optimization method LMI (Linear Matrix Inequality). Therefore, in this paper, we will take into account the advantage of using the two techniques in designing the Luenberger (full order and reduced order) and the functional observers in closed loop for estimation and control purposes. The simulation and experimental results are presented and discussed.
