Meltem TETİK¹ , FIRAT PARLAK²

In this paper, velocity vector control of the space vector pulse width modulation technique of the field oriented controlled(FOC) permanent magnet brushless synchronous motor(PMSM) will be provided according to asymmetric S-curve motion profile. The equations of S-curve motion profiles and their models are obtained in MATLAB/ Simulink. The flow-chart of the algorithms and their implementations are proposed and they are compared. In order to realize high precision control at high speed, the acceleration and deceleration control are discussed in detail and adopted. The experimental results are presented based on TMS320x28xxx. The control becomes more flexible. Simulation and experimental results show that the proposed approach of asymmetric S-curve profile method is more useful for fast, less jerk, vibration-less and smooth motion. So that the best dynamical performance of the motor is achieved.
