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 pe rformance 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 t able for the fuzzy logic controller (FLC). The proposed method for the fuzzy rules is based on the comparison of possible transient response s of the system output and the reference set point. Desired performanc e of the overall scheme was obtained by simulation, and the related re sults are given in the paper. (C) 1996 Elsevier Science S.A.
