| Tension control and fiber precise arrangement are the key technology of fiber-optic ringwinding machine. Tension control is to prevent the characteristics of the fiber changed andloose. Precise arrangement is to aviod the arrangement of the optical fiber ring defects, suchas overlap, clearance and so on. The controlling effectiveness directly affect the precision offiber optic ring that meet the application requirement of fiber optic gyroscope.The constant tension is maintained by line speed synchronization of the take-up capstanand the supply capstan in the process of winding. Due to the different in radius of the take-upcapstan and the supply capstan, and real-time change, they keep the variational proportionalrelation. For existing fiber winding equipment, fiber precision arrangement is synchronizedoperation of translation machine and spindle motor actually. Therefore, tension control andfiber precise arrangement can be summed up in the synchronization control between themotors speed.According to the relationship between motors and winding machine structure,simulations of relative coupling control are completed by means of the software of simulink.We analyze these several circumstances, which possible cause in winding speed process. Itimprove effectively the system response performance to fuzzy control and PI compensative.The simulation results show that Synchronous control mode adopted can need essentialrequirements to the optical fiber winding machine. |
