Analysis and suppression for impact fault of hybrid machine tool based on preview control

The impact fault of the hybrid machine tool were considered as the analysis object in this paper. The kinematics control principle of the hybrid machine tool was given as well as the causes of the impact based on the hybrid structure. The impact suppression method was given, which based on the preview-control algorithm. It was confirmed by experiment that the impact was reduced which was account for the application of preview-control algorithm and the performance of the control strategy was improved.
