Abstract
The high-frequency component mathematical models of an interior permanent magnet synchronous motor (IPMSM) were analyzed in two stationary reference frames. A rotor position sensorless control strategy was studied using carrier frequency component method. In order to provide continuous carrier frequency component signals, three-phase triangular carrier SPWM was adopted. The carrier frequency component current (CFCC) equations of the IPMSM were deduced under the modulating pattern. The peak expressions of CFCC contained the rotor position information. Based on the information, the position sensorless control of IPMSM was built. The simulation and experimental results demonstrate that the proposed method can realize position sensorless control of IPMSM over full speed range.
