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 sothat it can make a sensorless control. efficiency and facilities of step motor is more than othertypes of electromotor. therefore, the numbers of mechanisms and different types of turning canbe made into them. also controlling these motors is easier than other available motors. steppingmotor has been designed with oriented control in matlab software by using a simulink toolbox. in two methods above, current, torque and engine speed have been investigated by andwithout using kalman filter. the results showed that using field oriented control can eradicateresonance abnormalities. by using field oriented control, the maximum theoretical engineperformance can be achieved.
