| Summary: | 碩士 === 國立臺北科技大學 === 電機與能源研究所 === 88 === The objective of this thesis is to present the techniques for reducing the torque and speed ripples of a Permanent Magnet Synchronous Motor (PMSM) drive. The torque ripple of PMSM motor drive is reduced by using new switching tables which either invoking zero switching states or new switching states.
Two new switching tables are presented in this thesis. The first one invokes zero switching states for inverter control and turns the conventional three-level control into five-level control in the torque control loop. The second approach divides the area of space vectors into twelve sectors rather than six sectors in comparison with conventional approach.
Experimental results derived from a PC-based test system will be presented to show that the speed ripples of the implemented PMSM drive can be significantly reduced using the proposed new techniques.
