Figure 32. Feedback system stability analysis with actual system structure stiffness at 80%.
Figure 33. Feedback system stability analysis with actual system structure stiffness at 120%.
6.2. Simulation
The simulation is conducted using the same method as a feed-forward compensator simulation. Simulation
with an actual system that has exactly the same stiffness as the measurement, as shown in Figure 31, the sim-
ulation with an actual system that has stiffness 20% less than the measurement, as shown in Figure 32, and a
simulation with an actual system that has stiffness 20% greater than the measurement, as shown in Figure 33.
