Abstract
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.
