Abstract

The multiple synchronous reference frame controller is a common method for harmonic control in permanent magnet synchronous machines (PMSMs), but its low-pass filter deteriorates the harmonic regulation dynamics and system stability. The virtual winding structure, as a novel alternative, can quickly separate each harmonic by vector space decoupling transformation. However, past studies have often assumed that the virtual winding structure does not affect closed-loop system performance or stability. This article constructs the equivalent transfer function of the virtual winding structure of a PMSM under resistance asymmetry. It is revealed that this structure is essentially a special filter. The stability of the closed-loop system is then studied in both continuous and discrete domains. The influence of speed and controller bandwidth on the stability boundary is analyzed. A parameter design method for the harmonic controller is proposed to optimize dynamic response while ensuring system stability. Finally, experimental results show that the theoretical and experimental stability boundaries have an error of less than 4%, validating the accuracy of the stability analysis and the effectiveness of the parameter design.

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
