Abstract

In this paper, we concentrate on the cooperative disturbance rejection control of flexible riser systems corrupted by external disturbances. Fusing with disturbance rejection control strategy, auxiliary system, and Lyapunov theory, new controllers and disturbance observers are established to dampen the vibration and eliminate the effects of external disturbances. Considering all system states, the uniformly bounded stability of the considered system and the effectiveness of the proposed control scheme are realized through rigorous theoretical analysis. Further, the control performance is verified via numerical simulations by choosing the proper control gains.
