Optimizing speed and angle control of stepping motor by using field oriented control

In the present study, field oriented control of step motor implementation has been analyzed so that it can make a Sensorless control. Efficiency and Facilities of step motor is more than other types of electromotor. Therefore, the numbers of mechanisms and different types of turning can be made into them. Also controlling these motors is easier than other available motors. Stepping motor has been designed with oriented control in MATLAB software by using a Simulink tool box. In two methods above, current, torque and engine speed have been investigated by and without using Kalman filter. The results showed that using field oriented control can eradicate resonance abnormalities. By using field oriented control, the maximum theoretical engine performance can be achieved.
