Stepper motors are widely used in high accuracy positioning systems. However, the open-loop performance of these systems is highly influenced by the parametric and load variations and disturbances in the system. To improve the robustness of these systems closed loop micro-step positioning of hybrid stepper motor using Model Reference Fuzzy Adaptive (MRFA) control is being proposed. A reference model, whose output response is regarded as ideal, is considered as the mean for designing a fuzzy adaptive controller. Simulation results show that the proposedcontroller provides excellent tracking and disturbance rejection with regard plant parameter uncertainties.
