Fuzzy logic control for rotor field oriented control of a dual star induction machines

Abstract

This paper describes a rotor field oriented control of dual star induction motor (DSIM). The difficulty of control of the induction machine is the coupling between the torque and flux because; the changing of the load torque causes unquestionably the flux variation. However, to ensure a control separate of these two variables, the field oriented control is widely used in practice. The performance of this technique depends of changing parameters because adjusting parameters of conventional regulators is based on the system parameters. The variation of system parameters being inevitable, therefore the control loses its reliability. So, it is desirable to use independent regulators of parameters changes, order to, ensure the decoupling independently the variations of the parameters. For this purpose, we use controllers based on fuzzy logic controllers and we test system performance under the influence of parametric variations. The simulations results obtained from MatLab/Simulink are presented followed by a discussion.
