Improved Performance of a Fuzzy Control of Double Star Induction Motor Fed by Two Three-Phases Matrix Converters

The aim of this paper is to convince the non-linearity of conventional systems such as a rectifier-filter-inverter cascade and their most widely used direct conversion techniques which are used to power industrial multi-stator two-phase machines such as the DSIM. It is preferable to replace these systems with a direct and more compact AC/AC converter by three-phases matrix converter, while retaining good input-output waveforms and the possibility of adjusting the input power factor. The Park transformation and the orientation of the IFOC rotor flow can separate the strong coupling between the flux and the torque, in order to have the same performances as those of DC motors. On another hand we design a robust fuzzy logic controller FLC when these inference rules inspired by expertise, which remedy exogenous and endogenous variations such as the parametric variations of the DSIM machine. The performance and efficiency of the proposed FLC strategy used for controlling the three-phases matrix converters associated with the double star induction motor (DSIM) was illustrated by simulation using a Matlab-Simulink.
