Quadratic optimal self-tuning golden-section adaptive control of rigid-flexible couple system

Considering the high order and model complexity for rigid-flexible couple system, this paper will use characteristic modelling theory to simplify the modelling process. Besides, this paper will use goden-section adaptive control for the system. As it is difficult to adjust the parameters of goden-section adaptive control, this paper will use quadratic optimization control to realize self-tuning of goden-section adaptive control parameters. Compared with traditional PI and fuzzy PI, the results of physical experiments show that the proposed control has smaller overshot and better vibration suppression effect.
