Control and analysis of synchronous reluctance motors

Nonlinear mathematical models of synchronous reluctance motors are developed in the machine (abc) and in the quadrature, direct and zero (qd0) variables. Kirchhoff´s voltage law and Newton´s second law are used to find the differential equations which map the circuitry and torsional-mechanical dynamics. The Park transformation is applied in model developments to derive the differential equations in the rotor reference frame. A robust controller with nonlinear error and state feedback maps is designed to guarantee robust tracking, to ensure stability, as well as to attain disturbance rejection. Modeling results are given
