Permanent magnet synchronous motors and their relevant control techniques have become more and more prevalent in electric vehicle driving applications because of their outstanding performance. This paper studies a simple and effective sensorless scheme based on a current observer for a permanent magnet synchronous motor powered by a three-level inverter, which avoids the injection of a high-frequency signal and the observation of back-electromotive force. In this way, a current observer is constructed to observe d–q-axes currents by relying on an extended-current model. Thereafter, the position and speed of the machine can be extracted from two PI controllers associated with the d–q-axes current-tracking errors. Meanwhile, it takes into account the model predictive current control with neutral-point voltage balance to maintain the stability of the three-level inverter system. In general, this scheme realizes sensorless operation in a full-speed domain and is no longer limited by the types of inverter and method used.

The paper gives a brief introduction of the permanent magnet synchronous motor (PMSM). The author gives the mathematical model under the simplified conditions and the PMSM rotor and stator impedance matrix. Besides, the author used AMESim to build a synchronous motor model on the basic of hysteresis current control strategy and set the parameters. A simulation was carried out and advantages and disadvantages of hysteresis current control strategy were analyzed.
