| dc.description.alternativeAbstract | Recently, predictive torque control (PTC) is an extensively known control method in motor drives field. It is recognized as a robust control scheme used for high-performance control of Permanent Magnet Synchronous Motor (PMSM), which provides a rapid dynamic response. However, the high current harmonics and stator voltages in the permanent magnet when using direct torque control because of high torque and flux ripple cannot be overemphasized. This thesis shows a new scheme of minimizing the ripples of flux and torque of PMSM using PTC. The analysis of the equation following the relationship of equations involving torque and reference voltage was utilized by the conventional PTC. Thus, the ripple of both motor torque and flux shows a significant increase in the lower speed operation area. This thesis proposes a straight forward regulation duty ratio to be used to improved PTC. The method introduced calculates suitable motor torque minimization function to eradicate the ripple of stator flux and torque induced in the lower region of speed. The torque minimization function is introduced into the space vector pulse-width modulation block to decrease the ripple of motor torque produced in arrears to the set period. The proposed method substantially decreases ripples of flux and motor torque while creating in the transient state a quick step response of the motor torque. Results of simulation and experiment validated that the projected PTC approach effectually and significantly improves the dynamics of the system and noticeably decrease the ripple of the torque in contrast with the scheme of conventional PTC. | - |
