EXPERIMENTAL IMPLEMENTATION OF A FUZZY-LOGIC CONTROL SCHEME FOR A SERVOMOTOR

This paper describes the experimental implementation and evaluation of a rule-based, fuzzy logic control scheme applied to a d.c. servomotor. The advantages of the proposed scheme for servosystems are highlighted. Specifically, it is shown that the proposed scheme is simple in structure and can therefore be readily implemented as it requires the measurement of only one system variable. Typical experimental results obtained are presented and, for comparison purposes, results corresponding to a P.D. control scheme are also included. These results show that the proposed scheme is effective in controlling the shaft position of the servomotor under light and heavy load conditions.
