This paper presents a new position sensorless approach to permanent magnet brushless DC (PMBLDC) motor drive based on torque control for electric vehicle (EV) application. This method introduces a sector defined voltage vector-based switching logic in a constant torque region compared to conventional six-step trapezoidal control. The selection of voltage vectors, depends on the rotor position and the torque error, which eventually reduces the torque ripple. position information is obtained using stator flux linkage function, which shows superior dynamic performance at low speeds than the traditional back-EMF based method. Due to frequent commutation in the PMBLDC motor drive, the Lissajous pattern (locus) of the stator flux linkage deviates from ideal circle as in the case of a permanent magnet synchronous motor (PMSM), affecting rotor position estimation. Stator flux is kept constant while focusing only on the torque makes the controller computation simpler and faster. This approach keeps the stator flux linkage amplitude close to sinusoid and the position estimation tends to be more accurate. Low frequency oscillation in torque is minimized with this control, which is an advantage to EV or traction drive. The concept is well proved using detailed simulation analysis

This paper proposes a current controller for signal injection-based control schemes such as those for parameter identification and position sensorless control. In a conventional current control system with voltage signal injection, the separation of the injected frequency components from the current is carried out by using band stop filters. However, the separation is not accurate, especially when the system is in the transient state and/or when the current controller bandwidth is close to the injected signal frequency. This leads to distortion of the transient response and affects the stability of the current control system. The proposed controller estimates the injected frequency components in the current on the basis of a motor model by using the injected signal as the input. Therefore, accurate signal separation is accomplished even in the transient state. The current controller's stability and dynamic performance are improved significantly. Experimental results are presented to validate the proposed method. Factors that play an important role in the implementation of the controller, such as time delay and parameter variation, are discussed. (c) 2014 Wiley Periodicals, Inc.

A new hybrid position sensorless control method for reluctance synchronous machine drives is presented in this paper. The active-flux and arbitrary injection position estimation techniques are combined for the first time in this hybrid controller. The controller switches between estimation techniques depending on speed and load. A hysteresis region is implemented with phase-locked loop synchronisation for dynamic and stable changeover between estimators. Implementation of the active-flux method at high loads allows for extended sensorless torque capabilities at high speed.

Methods for sensorless control involving the injection of a high-frequency signal in the low-speed range of the Interior Permanent Magnet Synchronous Motor (IPMSM) have been proposed. However, audible noise is a concern in these methods. We propose a method to reduce the audible noise due to a high-frequency current by minimizing the injection signal amplitude suitable for IPMSM driving states.

This paper proposes a novel noise reduction method by injected frequency control for position sensorless control of permanent magnet synchronous motor (PMSM). The proposed method reduces acoustic noise caused by injected high-frequency voltage without reducing the accuracy of rotor position estimation. The proposed method is verified by numerical simulations and experiments using a 0.8kW-PMSM.

This paper presents a novel interior permanent synchronous motors (IPMSMs) model for position sensorless control. The proposed model has robustness with respect to magnetic saturation. Furthermore, this model can approximately estimate the maximum torque control (MTC) frame, which is possible to realize simple and robust sensorless control system. In addition, the sensitivity of inductance parameters in this model has also been discussed. Moreover, a position sensorless control system based on this model has been shown.

Traditional simplified flux linkage method is not suitable for the control of high-speed and super-high-speed SRM drives. In this paper, a high-speed SRM position sensorless control strategy based on an improved simplified flux linkage method to estimate the rotor position is proposed. This method has the capability of timely adjust the phase turn-on/ off angle at different speeds and can extend the maximum achievable speed for a constant DC-bus voltage. The principle of selecting the reference flux linkage on the basis of the SRM current-flux model to improve the precision of rotor angular position estimation is presented. The proposed control strategy is experimentally tested in two different SRM drives and the results show its feasibility, reliability and effectiveness, both for low-and high-speed SRM.

Precise estimation of position is essential in the control of switched reluctance motors (SRMs). Traditionally, the intersection of the adjacent inductance can be utilized to estimate the rotor position, however, magnetic saturation brings about variations in the intersection position when the motor is operated at heavy load. To solve this problem, this paper develops a sensorless position estimation strategy considering magnetic saturation and the embrace design. sensorless control approaches can be chosen interchangeably according to the characteristics of the intersection. Rotor position estimation is achieved by employing six typical inductance positions. No additional position sensor and other detection devices are required. Through simulation and experiment, the feasibility and validity of the proposed position estimation method are verified. The proposed sensorless method is verified for acceleration, constant operated state, and load mutation.

In this paper, one of the reasons of position estimation error is pointed out, i.e. the chattering of sliding mode observer (SMO). In order to reduce the buffeting of SMO, the permanent magnet synchronous machine (PMSM) sensorless control based on back electromotive force (EMF) observation method is analyzed. Continue function, saturation function, integral function and sigmoid function are compared with traditional switching function in detail. Low-pass filters (LPFs) are added to the output of SMO. A phase locked loop (PLL) is used to replace arctangent function to prevent SMO disturbance from being further amplified, and the corresponding angle compensation algorithm is studied. Through the comparison of simulation results, it is proved that the performance of sigmoid function is the best among these functions.

control system with position sensor is susceptible to the severe environment such as high temperature, humidity and vibration, which reduce the stability of control system. position sensorless control of permanent magnet linear synchronous motor need not position sensor so that it can use in abominable environment. According to three phases voltage and two phases current measured from motor, the position and speed of motor's mover can be estimated directly based on extended Kalman filter algorithm which is a kind of recursive algorithm. So position sensorless close loop control of PMLSM can be realized.
