摘要
In a short-span seeking-mode of hard disk drives, the resonance modes are getting crucial obstruction to meet the demand on high-speed data access. In this paper, a novel vibration suppression perfect tracking control (PTC) method is proposed based on controllable canonical realization. In the proposed method, it is assumed that plant is modeled as the rigid and primary resonance mode. By using this model, the feed forward controller is designed with PTC by multirate sampling control in order to suppress the primary vibration. Additionally, the higher-order resonance vibration is attenuated by using a trajectory named MHVT. The proposed method achieved 16% faster seeking than a conventional called MPVT method.
