“…However, when PMSMs are used for applications with moderate shaft dynamics, scalar (V/f and I-f) control is also popular due to their simplicity and ease of implementation. Two ways of using scalar control have been reported: as a startup method [7]- [14] and as a standalone control scheme for wide-speed-range operations [15]- [26].…”

This paper deals with I-f control of surface mounted permanent magnet synchronous machine (SPMSM) drives. Conventional open-loop I-f control is poorly damped and can only operate stably with positive d-axis current. An I-f control with a new current compensation loop is proposed to achieve stable i d = 0 operation in this work. The proposed method can be used for startup with a seamless transition to sensorless field-orientedcontrol (FOC), since i d = 0 operation is already achieved before switching to FOC. In addition, as the I-f control can now maintain stable i d = 0 operation against 100% rated load step disturbance from 10% to 100% rated speed, it could be a standalone control scheme for wide-speed-range operations. The proposed method is supported with detailed stability analysis and its performance is verified experimentally on a 2.7-kW SPMSM drive platform.

“…Although the key point of reference was to control SM-PMSM running at high speed with high inertial load, it was necessarily to tackle the standstill rotor position estimation. It was mentioned that no approach better than machine saliency for standstill rotor position estimation [19]. Reference [20] presented pulse injection method to estimate the initial rotor position of doubly salient PM motors.…”

The zero-speed rotor position estimation in surface mounted permanent magnet synchronous motor SM-PMSM represents a challenge due to the weak magnetic saliency in this type of motors. This paper presents a new method to estimate the initial rotor position of SM-PMSMs more simply and more accurately without any form of position or current sensors. It achieves this goal through an injection of three short width pulses and employing only the measurements of the motor terminal voltage responses, which fluctuate sinusoidally with the rotor position. Thereby, memory addresses, or dimensions of a look-up table, were created from the readings of the measured voltages. The memory was primarily loaded with 360 angles, each represents angle of rotor positions. The simulated MATLAB model and experimental results demonstrate the advantages. Comparing with the previous related publications, this research work has fulfilled two main contributions. The first is in achieving a rotor position estimation of resolution. The second is in eliminating the technique needed for detection of the rotor magnet polarity. The measured rates of error for the MATLAB model and the practical model were 2% and 5% respectively
