In this paper, an electric drive for positioning systems, consisting of two five-phase tubular permanent-magnet (PM) actuators fed by a single five-phase inverter, is described. The key idea is to combine together the technologies of tubular PM actuators and of multiphase drives. A proximate time-optimal positioning control scheme and a more conventional positioning control scheme based on PI regulators are presented. In both cases, the disturbances introduced by the parasitic coupling between the two actuators due to a realistic non-ideal sinusoidal distribution of the stator windings are considered and compensated. The behavior of the drive is assessed by means of experimental tests.

Abstract
In this paper, an electric drive for positioning systems, consisting of two five-phase tubular permanent-magnet (PM) actuators fed by a single five-phase inverter, is described. The key idea is to combine together the technologies of tubular PM actuators and of multiphase drives. A proximate time-optimal positioning control scheme and a more conventional positioning control scheme based on PI regulators are presented. In both cases, the disturbances introduced by the parasitic coupling between the two actuators due to a realistic non-ideal sinusoidal distribution of the stator windings are considered and compensated. The behavior of the drive is assessed by means of experimental tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
