A Modified Iterative Learning Control Approach for the Active Suppression of Rotor Vibration Induced by Coupled Unbalance and Misalignment被引量:1
《Chinese Journal of Mechanical Engineering》2024年第1期242-253,共12页Yifan Bao Jianfei Yao Fabrizio Scarpa Yan Li 
Supported by National Natural Science Foundation of China(Grant Nos.51975037,52375075).
This paper proposes a modified iterative learning control(MILC)periodical feedback-feedforward algorithm to reduce the vibration of a rotor caused by coupled unbalance and parallel misalignment.The control of the vibr...
