“…Generally, the rotating machineries are implemented to measure a rotational speed sensor such as a tachometer. The proposed design method was applied to design the parameters of three representative active vibration controls, namely, the second order filter (Herzog et al, 1996), the adaptive learning control (Xu et al, 2017;Bu et al, 2016), and the repetitive control (Hattori et al, 2000).…”

“…The first control method is using a second order filter based on the internal model principle (Herzog et al., 1996). The second control method is adaptive learning control (Xu et al., 2017; Bu et al., 2016) which updates the learning parameters in real time. The third control method is repetitive control which uses stored error signal during one cycle (Hattori et al., 2000).…”

In this paper, an optimal controller design method is proposed to compensate for vibrations caused by unbalanced force in the rotor system. The vibrations caused by unbalanced force are the major root cause of excessive whirling vibration in the rotor system, and it is important to compensate for the vibration to maintain its stable operation. The proposed design method can optimize a performance of the controller based on the vector locus of open loop characteristics on the Nyquist diagram. To verifiy the effectiveness, the proposed design method was employed for three typical active vibration control methods. The experimental results show that the proposed method can design the optimal parameters to compensate for the whirling vibrations of the rotor system.

In this study, an adaptive feed-forward cancellation (AFC) with frequency estimation algorithm has been developed to compensate for periodic disturbance at an arbitrary frequency. Conventional AFC was developed to compensate for periodic disturbance at a fixed frequency and cannot compensate for the disturbance in which the frequency varies in real-time. The proposed method can estimate the frequency of the disturbance in real-time by using the input and output signals of the AFC. It can compensate for the periodic disturbance at an arbitrary frequency. In addition, the stability of the feedback control system with the proposed AFC can be optimized at any frequency based on the vector locus of the open-loop characteristic on the Nyquist diagram. The effectiveness of the proposed AFC was confirmed in experiments compensating for whirling vibration, whose frequency varies in real-time in rotating machinery. The proposed AFC can estimate the frequency of the disturbance automatically and compensate for this adequately.
