Speed Control Methods for Stepper Motors

Robust Control of Permanent Magnet Stepper Motors using Only Rotor Position and Velocity

In this paper, a robust adaptive nonlinear dynamic controller is designed to achieve practical stabilization for position tracking error of a voltage-fed permanentmagnet stepper motor. The control design is an outputfeedback design that utilizes only rotor position and velocity measurements. Currents are not available for feedback. Adaptations are utilized so that no knowledge of motor paramete...

A Novel Vector Control Strategy For Bipolar Stepper Motor

The requirement of precise control in servo applications used in the digital systems led to the development of stepper motors. The precise and zero backlash operation of steppers extended its reach to various position control applications. The lack of requirement of sensors for position control applications was one of the main reasons for preferring stepper motors. Since the stepper motors were...

Stability analysis of piezoelectric beams

Piezoelectric materials are used in many engineering application. When modeling piezoelectric materials the standard assumption is that the electromagnetic field which is used to actuate the piezoelectric material is quasi static. In this paper we show that although the assumption of a quasi static electrical field is valid when one is interested in simulating a piezoelectric material, this ass...
