Robust deadbeat controller design using PSO for positioning a permanent magnet stepper motors

Abstract EN

This paper presents an application of a robust deadbeat controller for permanent magnet stepper motor.

This approach has been considered in order to assure robust stability and performance (disturbance rejection, reference tracking) with the presence of system parameters uncertainty.

The Particle Swarm Optimization (PSO) is used to tune the controller parameters by minimizing the cost function subject to H-infinity constraints.

It is shown that the designed deadbeat controller presents simple, low order, and robust position control for a permanent magnet stepper motor.

A two-phase motor is considered in this paper.
