An Application of Adaptive Fuzzy PID Controller in Packing Industry

In order to achieve high precision and stability in the measurement and weigh system of packing industry, base on traditional PID algorithm, this paper takes the fuzzy control theory into the controller, adopts this fuzzy-PID controller to the complex process with non-linear and strong interferes in packing and automatically switches between fuzzy algorithm and PID algorithm according to the error. This controller can improve control performance greatly and has been successfully used in a packing machine. The result indicates that the controller can get satisfied control effect.
