An improved adaptive control method for active balancing control of rotor with time-delay

抄録

In a high speed rotor system, active balancing control is an important method to improve performance and robustness. The time-delay will significantly increase the stability of the balance control system. Based on the dynamic model of rotor system with time-delay, a strictly positive real system is built to satisfy the stability conditions of adaptive control system in this paper. Furthermore, a feed-forward gain adaptive controller is designed. To improve the balance control of rotor system under both variable speed and constant speed, an adaptive control method is proposed. The advantage of this method against traditional control strategy is validated by numerical and experimental results.
