Modeling and simulation of high power open end winding based electromechanical actuator for aerospace applications

The paper proposes an open end winding PMSM based electromechanical actuator for altitude control through Thrust Vector Control. The open end winding configuration has the inherent advantage of applying the voltage directly to the phase thus enabling reduced voltage operation. The paper presents the modeling of the Open end winding PMSM and its drive. The closed loop position control is also modeled to validate the performance of the proposed scheme. The modeling and the simulation study is carried out in MATLAB/SIMULINK. The performance of the proposed system is evaluated through experiments and results are presented.
