Abstract

This paper introduces a fuzzy logic control (FLC) technique for controlling the speed of PM pancake DC motor . In this case the rotor speed of the DC motor follows an arbitrary selected trajectory . The rotor speed is given in a digital form over the control period, under different mechanical loading conditions. These are, constant load, linear load and quadratic load.
The control objective is to achieve accurate trajectory control of the speed , for motors of different parameters and different loading conditions. Simulation results show that the fuzzy logic controller (FLC) is efficient in speed tracking of DC motors in comparison with conventional PI controller.
