The paper presents a control method for disturbance attenuation of a rotating flexible beam using strain feedback. It is shown that the strain feedback, if appropriately used, can increase the stiffness of the flexible beam and, thus, attenuate external disturbances. The disturbance responses of the feedback controlled closed‐loop equation are also derived, and simulation results are provided to demonstrate the effect of the proposed control law.
