Abstract
The dual-driving feed mechanism (DDFM) has good feeding precision and reliability, but its synchronization error is unavoidable. A brand-new compensation strategy called active compensation is proposed in this paper for DDFM. The position errors of two axes are measured in advance and they are compensated to the control instructions respectively before feeding to eliminate the error. This strategy will reduce the synchronization error in DDFM. Firstly, the DDFM and the principle of synchronization error are introduced. Then, the simulation analysis of the active compensation strategy is carried out. Furthermore, the position error of DDFM is measured. Finally, the synchronization precision of active compensation strategy is compared against the master slave control. The results show the effectiveness of the proposed active compensation strategy.
