- Abstract
- This paper proposed a sliding mode fuzzy control - SMFC, for the two-phase step motors used in high torque and low speed position control applications. The design procedure is based on a sliding mode controller with boundary layer (SMC-BL). The procedure presented concentrates only on the fuzzy part since the rest part can be adopted from the SMC. This structure of controller (SMFC) generates a non-linear transfer characteristic in contrast with that of SMC with BL. The controller drives the step motor phase windings using field-orientation control rather than stepping mode. This method drives the motor at maximum theoretical performance.
