Abstract

This paper presents the design and experimental implementation of a
Fuzzy logic controller (FLC) for a DC servomotor speed and position
control. The motivation to utilize the FLC is its robustness against
model's parameters inaccuracy and uncertainty. The implementation of
the FLC algorithm is carried out by a low cost 8-bit microcontroller
instead of using expensive general purpose microprocessors which are
commonly employed in practice. This leads to a reasonable hardware
cost for such applications. The experimental results in terms of reference
tracking and disturbance rejection show high performance with the FLC
approach in comparison with PI and PD controllers designed for the
same purposes.
