Pak Se Yang, a researcher at Science Engineering Institute, reported a paper “Senseless vector control of PMSM with parameter error compensation” in SCI magazine "International transactions on Electrical Energy System"31(5).
In the paper, he carefully analyzed the drawback of preceding studies that error compensation algorithm is rather complicated and inefficient.
Based on it, he proposed a new method for enhancing the estimation and control correctness by estimating the current value based on motor model and compensating the element made by parameter error separately in the error compared with measured value.
