To improve corresponding control precision

this paper presents a new self-tuning fuzzy proportional-derivative controller (NST-FPDC) with real-time adjusting its proportional-derivative parameters

which realize the real-time adjustment of output scaling factor (SF). Moreover

a simple heuristic rule is defined on the normalized change of error of the controlled variable in order to make continuous variation in the close-loop gain. As a Tested result

the overshoot

rise time and other key performances of NST-FPDC are superior to more than 10% of the existing controllers

and some performances far better other controllers

which clearly verify the superiority and effectiveness of NST-FPDC.
