FLC IMPLEMENTATION ON A 8-BIT MICROCONTROLLER FOR DC MOTOR SPEED AND POSITION CONTROL

This paper presents the design and experimental implementation of aFuzzy logic controller (FLC) for a DC servomotor speed and positioncontrol. The motivation to utilize the FLC is its robustness againstmodel's parameters inaccuracy and uncertainty. The implementation ofthe FLC algorithm is carried out by a low cost 8-bit microcontrollerinstead of using expensive general purpose microprocessors which arecommonly employed in practice. This leads to a reasonable hardwarecost for such applications. The experimental results in terms of referencetracking and disturbance rejection show high performance with the FLCapproach in comparison with PI and PD controllers designed for thesame purposes.
