A method to form fuzzy logic control rules for a PMDC motor drive system

This paper investigates the application of a fuzzy-logic-based high performance speed control system for a permanent magnet direct current (PMDC) motor. The main contribution of this paper is the approach that is used to form the linguistic fuzzy subsets and fuzzy rule decision table for the fuzzy logic controller (FLC). The proposed method for the fuzzy rules is based on the comparison of possible transient responses of the system output and the reference set point. Desired performance of the overall scheme was obtained by simulation, and the related results are given in the paper.
