Vibration Control by Optimal Trajectory with Feedback System : Suppression of Residual Vibration

概要

論文の詳細を見る
Linear programming is used to suppress the vibration of a flexible structure in motion. When the structure is well modeled, this method is effective, but errors are easily introduced to the models ; therefore robustness becomes an important problem. Moreover, when the vibration under motion is controlled by a feedback system, the effect is not as good as expected, because of a restriction of state feedback gain due to the instability problem. In this paper, the feedback gain is obtained through optical-regulation theory on the premise that the feedback system is used with linear programming. Using this feedback system, an vibration control optimum trajectory method of a flexible structure based on linear programming is proposed. This method is more robust than that using only the optimal trajectory derived from linear programming. The validity of this method is shown through simulation and experiment.
