This paper concerns with vibration suppression control for three inertia
resonance system which can be used as the model for many moving
mechanisms widely used in industry such as steel rolling mills, flexible arms,
large-scale space structures, etc. Since the mechanical resonance which
causes vibration is unavoidable, especially at high speed operation, vibration
suppression plays a key role in improving the accuracy of the system. In this
research, a linear quadratic regulator-based speed controller with an
integrator that can effectively suppress the torsional vibration is applied to
control the system. Instead of using conventional state observer that is
sensitive to noise and model uncertainties, the extended state observer is used
to overcome the disturbance and uncertainty problems. Moreover, this
observer also gives us the load torque information that is used to improve the
load response. Simulation results show the effectiveness of the proposed
controller. In addition, the comparison to conventional PID controller also be
done to verify the advantages of the proposed approach.
