Abstract:

The wet compound device tension control system is a non-linear and time-varying system, and it is rather difficult to control constant tension. The traditional proportional-integral-dlfferentlal （PID） controller can not meet the requirements. The fuzzy PID control algorithm is based on the change ru ules of deviation e and deviation change rate ec to achieve the online coordination of the tension parameters, and establishes a fuzzy control monitorin g system table. Then it uses MATLAB to have a simulating experiment. By comparing the simulated curve of fuzzy PID with that of the traditional PID, we can see that the fuzzy PID controller has better anti-disturbance capability, and can obtain good adjustment property.
