FOC Based Control of a SynRM for Space Application

Synchronous reluctance motors (SynRMs) are getting precedence now a days in industries compared to its contenders like induction motors because of its higher efficiency and cold rotor construction. SynRM suffers from torque ripples and power factor issues. Non linear behavior in torque production averts its use in high efficient control and drive schemes. In this work, a control scheme which reduces the torque ripple and improves the dynamic response of a SynRM is proposed. An additional torque control loop is incorporated to the standard structure of field oriented control (FOC). The proposed system is simulated in MATLAB/Simulink and the results illustrate that there is significant reduction in torque ripple with the proposed method.
