Abstract

Due to the features such as high efficiency, small volume and high power density, super high-speed permanent magnet synchronous motor (PMSM) are becoming attractive in many fields such as high-speed micro-turbine generators, centrifugal compressors and pumps. V/f control is flexible and easy to be realized, moreover, voltage utilization ratio of SVPWM modulation is high, so the plan combined with V/f control and SVPWM modulation can be adopted for PMSM. The effects of the stator resistance and the dead-time on the control are generally neglected in traditional V/f control, which leads to that the low-speed performance is poor and the system is not stable at high speed. Based on considering the effects of stator resistance and dead-time, an optimal V/f control of the super high-speed PMSM is presented. Combined with the optimal V/f control and SVPWM modulation, soft starting and operating experiments for PMSM generator (105Kw, 61000rpm) are successfully implemented in the designed system of super high-speed gas micro-turbine based on DSP 320F2407A. The experiment results shows that this optimal V/f control is virtual and feasible for super high-speed PMSM. The proposed scheme provided dynamic stability and high performance of the super high-speed PMSM with an open-loop control.
