Robust QFT Controller Design for Positioning a Permanent Magnet Stepper Motors

Hazem I. Ali

Abstract—In this paper, an application of quantitative feedback theory QFT for permanent magnet stepping motor is presented. This approach has been considered in order to assure high control performance of the system. The QFT controller is used to design a simple, low order, and robust position control for a permanent magnet stepping motor. A two-phase motor is considered in this paper. Also the QFT controller is designed to give a robust stability and performance(disturbance rejection, reference tracking) with the presence of system parameters uncertainty. The objectives of the controller are verified in simulation.
