Vector Control Of Permanent Magnet Synchronous Motor (PMSM) Using Matlab/Simulink

Abstract

Nowadays, Permanent Magnet Synchronous Motors (PMSM) are designed not only to be more powerful but also to have lower mass and lower moment of inertia. Due to their high power density and smaller size, PMSMs have, in recent years, evolved as the preferred solution for speed and position control drives in machine tools and robots. One of the efficient control strategies for PMSMs is Vector Control. The rotor position is essential to achieve the vector control drive system of the Permanent Magnet Synchronous Motor. The proposed scheme must be verified by simulation. PMSMs are widely used in national defense, agriculture, and daily life. PMSM is a multivariable, nonlinear, and highly coupled system. The output torque and stator current present a complicated functional relationship. The magnetic field can be decoupled to achieve good control performance. It operates without slip frequency current, is less affected by rotor parameters, and is easier to implement vector control.
