Stepper motors are widely used in industrial and consumer applications due to low-cost,
high reliability, and open-loop control capability. Though open-loop features a simple …

A stepper motor is usually operated in position open-loop control for simplicity. However, in
order to improve the transient and steady-state performances of the stepper motor-based …

Stepper motors are employed in a wide range of consumer and industrial applications. Their
use is simple: a digital device generates pulse-bursts and a direction bit towards a power …

In this paper, an adaptive critic-based neuro-fuzzy controller (ACNFC) is developed for
robust and high-precision speed trajectory tracking of a hybrid stepper motor (HSM). The …

In order to meet the high safety requirement of high-level automatic steering mechanism for
commercial vehicle, a kind of steer-by-wire (SBW) system with redundant motors is studied …

Permanent magnet machines are not free from the interaction between magnets and the
stator and rotor slots, which causes an undesired disturbing torque. Such cogging or detent …

In this paper, we propose an advanced approach to improve the accuracy of stepper motors
based on an effective phase compensator. The proposed approach includes an adaptive …
