ロバストなモデル追従制御による機台振動系の振動抑制(機械力学,計測,自動制御)

This paper deals with a vibration and position control of a feed drive system, which is hindered by a vibration of the machine stand. The control scheme is designed based on a model following control method which can control the vibration of the machine stand without measurement a position of the stand. In order to assure good tracking performance as well as to guarantee robustness towards changes or uncertainties in the dynamics of the system, a discrete-time simplified model and a sliding mode control method are utilized for designing a robust controller. Experimental results demonstrate the good control performance and the effectiveness of the proposed control strategy
