“…These observers can reduce the current measurement noises due to the low-pass frequency response or improve the load transient performance based on the disturbance compensation. However, PMSM drives often contain other distortions from current measurement, inverters, and modulations, resulting in periodic position estimation errors in sensorless control [114].…”

“…It has a more adverse effect in the flux estimation since the pure integration calculation leads to infinite flux estimation [115]. The dc offset in the stationary-frame estimated flux or EEMF can further introduce electrical-frequency fluctuating errors in the rotor position estimation [114]. The disturbance in the estimated EEMFê (as an example) and the position estimation error…”

“…Adaptive bandpass position observers [114]- [116], [19], [37], [81], [124]- [128] are better candidates in dealing with the dc-offset issue compared to conventional low-pass position observers.

Rotor position and speed estimation methods are consolidated to reduce the cost and volume of permanent magnet synchronous motor (PMSM) sensorless control drives while maintaining high performance. Advanced nonlinear algorithms require accurate design for precise estimation tracking throughout the entire PMSM operation range. This paper presents a broad review of the main high-speed estimation methods for sensorless PMSM drives. First, the stability constraints and design methodologies of the main estimation techniques presented in the literature are discussed. In the second part, it is investigated the new observer design trends, which are used under non-ideal conditions, such as robustness to distortions, the effects of parameter variation, sensorless parameter estimation, and low sampling-frequency-to-speed ratio operation. Future trends on the design of observers for high-speed sensorless PMSM drives are also discussed.INDEX TERMS High performance drives, permanent magnet synchronous motors, sensorless control, state observer design.

In the sensorless control of a sliding mode observer (SMO)‐based permanent magnet synchronous motor (PMSM), a large gain is required to ensure the stability of the sliding motion. Nonetheless, this can lead to the unexpected chattering and degrade the precision of position estimation. To overcome this trouble, we have proposed a fixed‐time nonsingular terminal SMO (NTSMO). The convergence time is independent of the initial value. Firstly, a fixed‐time nonsingular terminal sliding mode surface is designed so that the current observation error fixed‐time converges to zero, and the singularity issue can be averted. Secondly, via the phase‐locked loop tactic, the rotor position and speed are calculated from the measured back electromotive force. Thirdly, a Lyapunov function‐based proof is utilized to assure the stability of the observer. Finally, the validity of this method is confirmed by simulation tests and experiment results.
