Abstract
Compared to the linear motor model, the flux linkage motor model has a higher degree of similarity to real PMSM. A practical approach for implementation involves extracting condensed data from Finite Element Analysis (FEA) results to construct look-up tables. However, in certain real-time hardware applications, memory space is limited, making it impossible to accommodate large tables. To overcome this limitation, a correction method is proposed in this article to enhance accuracy while keeping the table size unchanged. Consequently, the data point in two axes of look-up table will be non-uniformly distributed. This unique characteristic of the look-up table contributes to higher simulation accuracy.
