Indirect-Rotor-Field-Oriented-Control of a Double-Star Induction Machine using the RST controller

This paper focuses to apply the RST controller on the indirect-rotor-field-oriented-control (IRFOC) of a double star induction machine (DSIM). After fixing the reference models, some algebraic conditions permits to design the current and speed controllers. This step consists to find three polynomials R, S, T of the controllers by solving the Diophante equation. The RST controllers can ensure robustness against uncertainties of mechanical and electrical parameters of the motor. It also offers further degrees of freedom upon the choice of the dynamic of the system. Simulations and analysis will be developed to prove the effectiveness of the study.
