Optimal State Feedback

An optimal state feedback controller based on H2 norm is proposed for attenuating the belt vibration caused by loading disturbance in a class of image transfer belt which is widely applied in multi-color printers. Based on the simplified mechanical model of the image transfer belt unit, the presented controller acts on the actuating torque generated by a direct-current motor and optimizes the defined variables related to the quality of the original image formation. Simulation results responding to a periodic loading disturbance ascertain its efficacy with comparisons of the conventional speed control. It is certified that the image transfer belt unit is successfully maintained in a satisfying condition with effective vibration attenuation under the proposed control architecture.
