Abstract :
The estimate of the rotor position of inner permanent magnet synchronous motor (IPMSM) by using the method of high-frequency signal injection is discussed in this paper. The simulation of the model with MATLAB is carried out. The impact of the non-linear of the inverter, especially the dead zone time is analyzed. The some compensate measure is given. The result of the simulation shows the correctness and feasibility of this method.
