Different from the traditional method of the interior permanent magnet synchronous motor (IPMSM), the sensorless maximum torque per ampere (MTPA) control scheme in this paper does not need two observers for rotor position and d-q axis inductances, respectively. It only needs an adaptive sliding mode observer (ASMO) based on the extended flux (EF) to realize double-loop control and MTPA operation simultaneously. The adaptive mechanism of rotor speed is designed to ensure stability of the ASMO. The rotor position and the difference between d-axis and q-axis inductances are obtained from the estimated EF to acquire the MTPA points when the position sensor of the IPMSM is absent. The proposed scheme is realized on a 20kW IPMSM where the sensorless control performance and the MTPA control performance are tested. The effectiveness of the proposed method is verified by the experiment results.

“…However, encoders are expensive and susceptible to electromagnetic interference. In order to increase reliability and reduce cost, various advanced sensorless control structures have been proposed to remove the encoder in the drive system [1][2][3]. In general, the rotor position is obtained based on current measurements in these schemes [4][5][6][7][8][9][10][11][12].…”

The zero‐voltage vector (ZVV) method is widely employed to restart a free‐running permanent magnet synchronous machine (PMSM) stably in a sensorless drive system due to its simple implementation. However, in the conventional method, it is hard to determine the action time and interval time of ZVV pulses, which may result in overcurrent. Moreover, the estimation accuracy is susceptible to current measurement noise. To cope with these problems, an enhanced ZVV method based on two feedback loops is proposed. With the proposed strategy, an inner closed loop is constructed to regulate the action time of the ZVV pulse by keeping the current amplitude at the reference value, which prevents the overcurrent. Meanwhile, the reference value of the current amplitude is adjusted automatically based on the outer loop to determine a suitable interval time of the ZVV pulse. Furthermore, the phase‐locked loop technique is exploited to extract rotor speed and position. The feasibility of the proposed method is verified under simulation and experimental results with a 5.5 kW sensorless PMSM drive system.
