Study On Fuzzy-PID Tension Control System For Numerical Filament-winding

After analyzing the structure and development of current tension control system, a new filament winding tension control system was developed, which is based on the open NC system PMAC(Programmable Multi-Axis controller). The main works in this paper are as follows:1. Tension control close loop system was set up based on the PMAC & IPC with a new tension feedback sensor composed of rotary encoder, mechanical arms, with an actuator DC torque motor. As a necessary step, the working theory, the static and dynamic characteristic, the mathematical model of system were discussed upon this scheme.2. A novel proportional-integral-derivative (PID) self-adaptive controller by fuzzy adaptive mechanism for the tension control of filament winding system was presented, and the simulation based on MATLAB of this control algorithm was conducted to study the effect compared with traditional PID controller. The comparative study shows that the overshoot and the fluctuation of tension decrease considerably. Furthermore, the specific realization of this algorithm is designed for actual purpose.3. On the basis of the control software frame, each main function module was introduced and analyzed. Data acquisition, implementation of control arithmetic, system communication and pictorial representation of data were introduced emphatically.4. In order to ensure the stable tension control to the fiber during the actual winding process, the system modularizing experimental rig was build up. And the dynamic test was done after that. According to the experiment results and analysis, the performance of the system satisfied all the rudimental requirements.
