– A predictive control of a brushless DC generator supplying a load connected to the DC-link capacitor is presented in this paper. The tracking characteristic of the prime-mover is considered for setting the reference value of the electromagnetic torque developed by the generator. This reference is assumed in order to determine the switching pattern of the AC/DC converter, at each sampling period, under the constraints of minimum Joule losses and minimum torque ripple. A conversion system is computer simulated in Matlab-Simulink environment and the results are compared to those of the traditional generator-rectifier system. The comparison reveals that the torque ripple minimization is achieved and more power can be delivered by using the proposed control technique with respect to that of traditional system.

Abstract
– A predictive control of a brushless DC generator supplying a load connected to the DC-link capacitor is presented in this paper. The tracking characteristic of the prime-mover is considered for setting the reference value of the electromagnetic torque developed by the generator. This reference is assumed in order to determine the switching pattern of the AC/DC converter, at each sampling period, under the constraints of minimum Joule losses and minimum torque ripple. A conversion system is computer simulated in Matlab-Simulink environment and the results are compared to those of the traditional generator-rectifier system. The comparison reveals that the torque ripple minimization is achieved and more power can be delivered by using the proposed control technique with respect to that of traditional system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
