First, a standard PMSM drive with single-phase switch-mode rectifier (SMR) front-end is established. The necessary control schemes are designed to yield satisfactory motor driving performance with good line drawn power quality. Specifically, a simple robust current error cancellation controller is applied to yield closer current waveform tracking control. In digital control aspect, the control algorithms of two power stages are realized in a common digital signal processor (DSP) based digital control environment. And more specifically, the domestic manufactured DSP is employed to promote its application ability in AC motor drive. As generally recognized, torque ripple and vibration reductions are helpful in the reduction of acoustic noise of a motor drive. Hence next in this thesis, the possible origins of torque ripple and vibration of PMSMs are explored, and some remedies in their reductions are also understood. Then the experimental studies concerning some affecting factors for the established PMSM drive are made. And the reduction control approach via robust torque current command injection is proposed and evaluated its effectiveness. Finally, a sensorless control scheme for PMSM drive is developed in this thesis. The PMSM rotor magnet polarity is first identified using the proposed intelligent approach. Then it is smoothly started in synchronous motor mode in unidirection. Meanwhile the motor back-EMF is estimated by the developed robust current control scheme, and it is employed for performing the PMSM sensorless vector control. Theoretic basis of the proposed non-reversible starting approach, its operation characteristics and possible improvements in methodology and scheme are described in detail. And furthermore, a commutation instant tuning scheme is designed to yield equivalent maximum torque per ampere characteristics. Chang-Ming Liaw 廖聰明 2008 學位論文 ; thesis 166 zh-TW |
