Self-tubing fuzzy control for Flexible Circuit Board testing machine

The process of tension control in material testing by using the Flexible Circuit Board testing machine (FCBTM) is featured with multi-variable, nonlinearity, time delays and time variation. In order to ensure the tension precision, speed and the stability of the test results, this paper establishes an accurate system model for the FCBTM, in which a novel three-dimensional fuzzy self-tubing PID fuzzy controller is designed. Specially, the simulation results show that the proposed self-tubing fuzzy control method is not only robust to the external disturbance but also with more excellent dynamic and steady-state characteristics than traditional ones.
