| Research Abstract |
This study has developed robust-adaptive control of IPMSM for various applications. To avoid degradation of control performance due to magnetic nonlinearity in IPMSM, this study has realized (1) robust position estimation using unknown input observer, (2) a new mathematical model with less sensitivity to magnetic nonlinearity, yielding robust performance improvement in position sensorless control of IPMSM.
