Speed Control of Buck-converter Driven Dc Motor Based on Smooth Trajectory Tracking

This paper presents the detailed account on the control design of a buck converter driven dc motor. Proportional-integral (PI) and proportional-integral-type fuzzy logic controller (PI-type FLC) are the techniques proposed in this investigation to control the speed of a dc motor. The dynamic system composed from converter/motor is considered in this investigation and derived in the state-space and transfer function forms. Complete analyses of simulation results for PI and PI-type FLC technique are presented in frequency domain and time domain, respectively. Performances of the controller are examined in terms of duty cycle input energy, armature current and angular velocity. Finally, a comparative assessment of the impact of each controller on the system performance is presented and discussed.
