Abstract :
This paper presents simulation and experimental studies of permanent magnet synchronous motor (PMSM) control methods, including vector control (VC) or field oriented control (FOC), direct torque control (DTC) and model predictive control (MPC). The steady-state performances under a range of sampling frequency (1.5kHz-20kHz) of each method are performed in Matlab/Simulink and dSAPCE system. A comprehensive analysis based on these tests shows that the efficiency of control methods (sampling frequency vs. torque ripple) decreases along with the increase of sampling frequency.
