| Abstract: | The rotor position estimation of permanent-magnet-synchronous motor based on high-frequency signal injection needs a perfect injection current, so it will degrade the estimation accuracy due to the sample white-noise , which is hard to remove by ordinary digital filter. Kalman filter is a powerful tool to cope with this kind of noise. This paper discusses the design and simulation of a kalman filter and runs it in a DSP-controlled motor, the experimental result shows that the kalman filter works well. |
