A HEURISTIC SELF-TUNING FUZZY CONTROLLER

In this paper, a self-tuning fuzzy controller based on the tuning of scaling factors is presented. The tuning schemes are tuning the scaling factors by individual tuning rules. The tuning rules are transformed into numeric tuning tables by applying suitable membership functions so that the adjustings of the scaling factors are merely matrix mappings. Since the tuning rules are constructed with the control signal and the output error and change in output error of the plant as their antecedent parts, the tuning processes have the advantage of real-time property. Simulation results with a perturbed servo system and the inverted pendulum system as the controlled plants show the performance and adaptivity of the proposed controller.
