Fuzzy Supervisory Predictive PID Control of a Plastics Extruder Barrel

The describes the design of single-loop fuzzy supervisory predictive PID controllers for a plastics extruder barrel. A fuzzy supervisory shell is proposed to improve the set-point tracking performance of the proposed PID method by appropriate adjustment of the weighting term for the control effort. Experimental results show that the proposed method is capable of giving a good result on the barrel.
