This article presents a synthetic sensorless control strategy combining the inductance and simplified flux models for switched reluctance motors (SRMs). First, the initial driving phase is determined by improved phase inductance comparison (IIPC). Second, the SRM's driving signal is obtained by the improved double inductance threshold (IDIT) method to ensure a reliable and smooth start. Third, to address the challenges posed by the large memory resources and lengthy execution time of the conventional table searching method for flux, the Fourier polynomial is employed to calculate the reference flux. Then, by comparing it with the real-time flux, the Hall signal can be obtained to estimate the rotor position. Moreover, an angle adaptive adjustment method is proposed to satisfy the requirements of different speeds and working ***, a six-phase 12/10 pole SRM is used to verify the effectiveness of the proposed sensorless control strategy.

Electromagnetic launch system has characteristics of high acceleration, intense vibration shock, and strong electromagnetic interference, which may damage the position sensor and interfere with signal processing, thus affecting both safety and stability of the system. To solve the aforementioned problems and reduce the system cost, one position sensorless control method via a reduced-order observer based on the linear quadratic regulator and Kalman filter (LQR-KF) is proposed for the dual three-phase permanent-magnet linear synchronous motor (DTP-PMLSM) adapted to electromagnetic launch in this article. The fast solution of Kalman gain in the LQR-KF observer is completed by the LQR, which can eliminate the higher order matrix operations in sensorless control based on the traditional extended Kalman filter, and greatly simplifies the computational effort. Compared to the traditional method, the observer order in the new algorithm can be obviously reduced by variable substitution of the nonlinear system, and the observed accuracy can be greatly improved by eliminating the need for Taylor series approximation of the nonlinear system. Comprehensive field-circuit coupling simulation and experiments based on a 480-kW DTP-PMLSM have fully demonstrated the simplicity and accuracy of the proposed method in this article.

position sensorless control of SRMs Based on Improved Sliding Mode Speed controller and position Observer

IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS 2025年第1期72卷 100-110页

This article presents a sensorless control strategy based on an improved sliding mode speed controller (SMSC) and sliding mode position observer (SMPO) for switched reluctance motor (SRM). The proposed method could reduce the motor speed response time and improve the estimation accuracy of rotor position information. First, an improved SMSC based on time-varying function (TVSMSC) is proposed to reduce the influence of internal parameter disturbance and external load disturbance so that the SRM's actual speed can accurately track the reference speed. In order to reduce the initial harmful peak generated by the SRM during initial startup, a time-varying function is introduced into the new approach rate. Then, to obtain more accurate rotor position information, an SMPO based on the inductance model is used to estimate the rotational speed and rotor position in real time. Finally, the experimental validation is performed. The results show that the proposed strategy can effectively reduce the overshoot and speed transient response time while maintaining high robustness and high estimation precision of rotor position.

The aim of this article is an attempt to provide a more credible control mode or a fault-tolerant control strategy for permanent magnet synchronous motor (PMSM) drives when an unexpected failure occurs to the current or position sensor. Considering that, a position sensorless control method that uses only one current sensor is proposed. Different from a traditional position sensorless control scheme that utilizes additional current sensors to obtain information of multiple phase currents, only a single current sensor (SCS) arranged on one of the current branches is included among the whole control circuit. Three-phase currents are reconstructed by sequentially sampling the SCS under specific voltage vectors, and directly employed for motor position estimation. A nonlinear position observer established according to the gradient descent is adopted. Focusing on the special current-acquisition pattern in this article, a step-size optimization method based on golden section search is proposed to minimize position estimation error. The experimental results reveal that the method in this article is comparable to the traditional full-current-sensor method in terms of position estimation, which confirms the fault-tolerant capability as one certain sensor of the control structure malfunctions.

Dual three-phase interior permanent-magnet synchronous motor (IPMSM) drives have received more attention by the merits of better fault-tolerant capability and lower torque ripples. To improve the reliability of the system against failures in position sensor, it is necessary to investigate the position estimation method for dual three-phase IPMSM drives. The high-frequency (HF) signals injection is utilized for position estimation in three-phase IPMSM drives during low-speed operation region. However, the torque ripples are inevitable owing to the mixing of fundamental and HF components in the same control space for three-phase IPMSM drives. In this article, the position sensorless control method has been proposed by injecting HF square-wave voltage in the harmonic subspace for the dual three-phase IPMSM drives. Since the harmonic subspace is decoupled from the torque subspace, the torque disturbance can be mitigated well with the proposed HF signal injection-based position sensorless method. Moreover, the digital filters in signal extraction and current feedback can be avoided and the signal separation process becomes easy with the proposed method. The experiments have been conducted to validate the performance of the proposed method.

This study focuses on the position sensorless control method for Switched Reluctance Generators (SRG) using a state observer. SRG is being considered as a cost-effective alternative to permanent magnet synchronous generators, particularly in renewable energy applications such as hydroelectric power generation. Accurate rotor position control is required for SRG, and traditionally, position sensors have been used to achieve this. However, the use of sensors increases costs and reduces durability in outdoor environments. This study proposes a sensorless control method that estimates the rotor position based on electrical signals using a state observer, eliminating the need for physical sensors. A linear state observer model for SRG was constructed, and its performance was verified through simulations under both low-speed and high-speed operating conditions. The simulation results demonstrated that the proposed method could accurately estimate the rotor position with minimal error. This study contributes to cost reduction and improved reliability of SRG in the field of renewable energy.

This paper proposes a new position sensorless method for switched reluctance motor (SRM) drive control based on a sliding mode observer using nonlinear Fourier flux linkage model. First, to obtain an accurate mathematical model of SRM for establishment of sliding mode position observer (SMPO), an analytical method based on Fourier polynomial function is introduced to regress the nonlinear relationship between flux linkage, position and current. Then, a new SMPO is designed in detail to estimate the rotor position, including the establishment of SRM model of sliding mode observer, and analysis of estimation error and convergence conditions of SMPO. Finally, position sensorless control of SRM drive based on SMPO is carried out in terms of accuracy and robustness in simulation. Experiments are also given on a dynamic testing platform to verify the effectiveness of the proposed position sensorless scheme.

position sensorless control of interior permanent magnet synchronous motors (IPMSMs) is of great importance for the sake of the cost reduction and robustness improvement. An improved position sensorless method based on adjustable high-frequency (HF) square-wave voltage injection has been proposed for the IPMSM drive under zero- and low-speed regions. The general detection method of position from positive- and negative-sequence HF current response has been developed by the simple algebraic operations of data at some adjacent sampling instants. In addition, the proposed method not only can retain the advantage of the removal of low-pass filters in current feedback but also can increase the voltage margin of inverter with adjustable frequency setting of HF signal compared with existing square-wave voltage injection methods. Comprehensive experimental results have been given to verify the proposed theoretical analysis.

In this study, a high-frequency pulsed voltage signal is injected into the d axis of the synchronous rotating frame of a surface-mounted permanent magnet synchronous motor (SPMSM) with insignificant salient pole effects. Through detection and analysis of the high-frequency current response signal at the stator side, the rotor position and speed information can be extracted to achieve sensorless control of the motor. A passive controller with a port-controlled Hamiltonian dissipative (PCHD) structure is designed by using the principle of energy forming and the method of interconnection-damping configuration. A 2.2-kW SPMSM experimental platform is built for experimental verification. The simulation results show that when the motor is miming at a low speed, the proposed pulse-induced high-frequency voltage signal injection method exhibits a higher accuracy of rotor position and speed estimation. The passive controller can suppress the fluctuation of the motor starting speed and demonstrates a better ability to resist load disturbance.

Due to detection errors, motor parameter deviations, and other uncertainties, traditional motor flux estimation models suffer from the complications of DC bias and high-order harmonics. To address these issues, two flux observers, the second-order generalized integrator flux observer (SOIFO) and the second-order SOIFO, are designed for position sensorless control of permanent magnet synchronous motors (PMSMs). The position sensorless control of PMSMs based on an improved second-order SOIFO is proposed in this paper. The proposed method enhances the frequency-locked loop (FLL) in the observer by introducing a double-axis frequency-locked loop (DFLL), which improves the dynamic performance and disturbance rejection capability of the flux observer. By replacing FLL with DFLL for angular frequency estimation, the method effectively eliminates second-harmonic interference while reducing estimation delays, leading to faster and more accurate rotor position estimation in the second-order SOIFO. Additionally, the improved observer demonstrates enhanced robustness against disturbances, ensuring more stable position sensorless control. The effectiveness of the proposed approach is validated through both simulations and experimental comparisons.
