“…Although it can effectively improve the robustness of the system to inductance parameters, it increases the amount of mathematical calculation of the system design, increases the calculation load of the system, and reduces the stability of the system. The model reference adaptive method proposed in the literature [10,11] is simple in structure, but the system is easily affected by load and motor parameter changes.…”

A new sensorless speed control system for a fractional-order terminal non-singular sliding mode surface-mounted permanent magnet synchronous motor is proposed. The fractional terminal non-singular sliding mode surface, which can converge in finite time, is designed by combining the fractional-order control theory with the terminal attractor concept. Then, a new control rate is proposed to reduce system buffeting. Secondly, an adaptive back electromotive force filter is designed to reduce the harmonics in the sliding mode function estimation and improve the observation accuracy. In addition, the theoretical analysis of the designed system proves that the system can converge in a finite time. Then, a fraction-order phase-locked loop with variable factors is designed to make the system more capable of tracking the rotor. Finally, a simulation and experiment platform is built, and a comparison experiment is carried out, which proves that the designed algorithm has a stronger rotor position tracking ability and a better dynamic performance of the system.

The fault-tolerant control system (FTCS) for a permanent magnet synchronous motor (PMSM) is presented and an analysis of speed sensor faults is proposed in this paper. The detection and compensation of speed sensor faults is based on the simple comparison of the measured signals with the signals estimated by reduced-order sliding mode observer (SMO). The focus of the work is on the presentation of simulation and experimental research for the most common speed sensor failure types: complete signal loss, gain error, and measurement noise. Additionally, an analysis of different operating conditions of the PMSM drive system is presented, which highlights the system's behaviour under various conditions. The presented algorithm enables the fast detection and compensation of failures with very short detection times, making it a versatile solution for a PMSM drive system and improving its overall reliability.

“…Two main methods of PMSM sensorless control are high frequency injection method (Brandstetter and Krecek, 2014; Jang et al, 2003; Lin and Zhu, 2005; Yang and Lorenz, 2011) and back ElectroMotive Force (back-EMF) method (Aydogmus and Sünter, 2012; Corradini et al, 2010; Liang et al, 2018; Zhao et al, 2018), respectively. High frequency injection method is relied on saliency tracking (Brandstetter and Krecek, 2014).…”

“…For example, in Zhao et al (2018), the Model Reference Adaptive System (MRAS) observer estimation algorithm combining with the Fuzzy Logic Control (FLC) is put forward to estimate the rotor speed and the rotor angle, but the model parameters adaptation of MARS is difficult to achieve. Extended Kalman Filter (EKF) method is proposed in Aydogmus and Sünter (2012), however, heavy online matrix computing is necessary.…”

An adaptive second-order sliding-mode observer based on Super-Twisting Algorithm (STA-SMO) to estimate rotor position and speed of permanent magnet synchronous motor (PMSM) is proposed in this paper. The advantages of the proposed observer algorithm are reflected in small chattering, high tracking accuracy, good robustness to parameters change and external disturbance in wide positive and reversal speed range. The Lyapunov stability of the system is proved. A new perturbation term form is employed and according to the stable condition of STA-SMO, the adaptive sliding-mode coefficients related to absolute value of estimated speed are deduced to guarantee the performance mentioned above in wide positive and negative speed range. In order to extract rotor position and speed in both speed range from the adaptive STA-SMO, an improved conventional phase-locked loop (IPLL), which is more accurate, is studied and its non-linear dynamics are analyzed in detail to prove the effectiveness of the IPLL theoretically. In the end, the effectiveness of the adopted adaptive second-order sliding-mode observer with IPLL structure is verified through simulations. Simulation results show that the position error and chattering of the proposed adaptive observer are decreased more than 25% and 50% compared with conventional SMO and STA-SMO in wide positive and negative speed range. Meanwhile, the proposed system still has good estimation performance and strong robustness with torque and parameters variation.
