With the characteristics of non-linearity, large time delay, and strong disturbance, the web tension control is the main difficulty of the re-winder electrical control system. The conventional PID algorithm can not achieve good performance index when the re-winder is working under acceleration or deceleration. The new algorithm based on fuzzy control adaptive PID algorithm could solve this problem,...
This paper is aimed at looking into the PID control design of systems with large time-delay. In a preliminary step, the system is modeled by a time-delay second order model. Time constants of the PID controller are determined on the basis of the obtained model using the pole compensation technique. The PID proportional gain results from the minimization of the settling time by the use of genetic algorithms...
