- Permanent magnet stepper motors (PMSMs) are widely used in high-performance applications where position accuracy and torque smoothness are important issues. In this thesis, a eld oriented control (FOC) without
direct-quadrature (DQ) transformation controller is proposed to improve the performance for PMSMs. To enhance the properties of position tracking, a position proportional-integral-derivative (PID) is proposed. To reduce the position tracking lag, a velocity feed-forward is in addition to the position PID feedback. For the desired phase currents, two current proportional-integrals (PIs) are used to compensate the back-emfs. The experimental results show the performances of three control modes: the microstepping control mode, the position PID with current PIs control mode and the proposed control mode. The results also illustrate that the proposed controller eectively
achieves FOC for PMSMs without DQ transformation.
