At equilibrium point (3091:85; 3091:85; 0:023085; 2:97056; 37:132; 0; 247:76) and at different initial conditions like (100; 0; 11:01; 0; 0; 0; 0), (100; 0; 11:01; 11:01; 11:01; 0; 0), (110; 0; 15:01; 0; 0; 0; 0), (130; 0; 20:01; 0; 0; 0; 0) the controllability and observability of the graph is approaches to zero, so system not work like close loop for feedback design are shown in (Figure 1 & 2).
