Research on technology of lateral position control in composites tape winding

Correcting the tape deviation is one of the key technologies for composite winding forming. To achieve the correction control with high accuracy and high robustness, we first analyze the tape motion characteristics during the winding process. Then a simulation model of the rectification control system for tape winding is established with the parallel-roller rectification system. The model shows that tape winding rectification movement is a dual-input time-varying system. Winding tension and winding speed correction will change the system parameters. For this, fuzzy controllers are used to do simulation model of the rectification system for tape winding. The results and their analysis indicate preliminarily that fuzzy control is better than PID control. With the rectification system parameters changeable, the rectification precision of fuzzy control can be within 0.6 mm.
