Simple Tuning of a Fuzzy Pulse Width Modulation Controller for a DC Motor Application

The aim of this work is to evaluate the effectiveness of a Simple Tuning algorithm applied on a Fuzzy Pulse Width Modulation controller in a real situation with DC gear motors. The fuzzy logic model proposed to control motor’s no-load speed consists in 25 rules based on Mamdani Fuzzy Inference System. A hardware implementation and an interface are designed for controlling the plant. In addition to the Simple Tuning process, another algorithm is presented to get the vector of operation points of each input and save the new one after applying such process. The experimental results are presented at the end of this paper.
