摘要：In this paper a Reusable Launch Vehicle in atmospheric phase is considered. A disturbance observerbased PD controller is proposed for controlling the attitude of the system considered. This method is an effective wayof achieving disturbance rejection and robustness to plant uncertainties. The disturbance observer based control is usedfor observing the flexibility dynamics and stabilizing the flexible mode RLV. The disturbance observer makes theactual flexible plant dynamics similar to that of nominal rigid body within a limited frequency range. The classical gainstabilization approach for stabilizing bending mode is also presented. Both methods are compared and advantages ofdisturbance observer based PD control over the gain stabilized PD control are discussed.
