In the field of the manufacturing industry, it has been often discussed that high-mix low-volume manufacturing is required to meet a variety of customer needs. In such a situation, cellular manufacturing and U shaped production lines are often adopted. Linear synchronous motors (LSMs) are appropriate to realize U shaped automation lines because of its strong features such as flexibility of layout, high efficiency and position control performance. However, a problem seems to lie in the fact that LSMs need a position sensor which is expensive and has less durability. For this reason, the position sensorless control for LSMs is required. In addition, the method should be easy to apply to all kinds of LSMs. Specifically, the method should require no saliency and be apply to a LSM which has a complex track including curvilinear section. Based on such a background, this paper presents a position estimation method for a Linear and Curvilinear Synchronous Motor with an accelerometer which is inexpensive and easy to attach to LSMs. As the proposed method in this paper does not require any motor saliency, it can be quickly applied to all LSMs. In this paper, the proposed method is shown and verified by experimental results.

This paper proposes an Extended State Observer (ESO) to achieve the sensorless position control of permanent-magnet synchronous motor (PMSM). An Extended State Observer (ESO) is built according to the back electromotive force (EMF) model. It uses a nonsmooth2 structure to observe all states of the controlled object and the inside and outside disturbance of the system. Original system can be converted into linear certain system by this. Furthermore, stability and convergence analysis of the closed-loop control are given based on the Lyapunov stability theory. Simulation results verify the asymptotic convergence of ESO.

Methods for sensorless control involving the injection of a high-frequency signal into the low-speed range of an interior permanent-magnet synchronous motor (IPMSM) have been proposed. However, audible noise is a concern for 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.

Frequency-Weighted Angle Compensator for position sensorless Permanent Magnet Synchronous Motor control

An angle compensator is proposed on a basis of an angle estimation of a permanent magnet synchronous motor. The angle compensator consists of frequency weightings for a speed reference and an angle estimate. Frequency characteristics using a bandpass filter for the compensator are shown. The characteristics are discussed in a comparison with those using the other filters. The compensator gives a controlled angle from the speed reference and angle estimate even in high-frequency region. Numerical simulations and experimental results show tracking performance with an adequate use of the reference and reducing noise even in high-frequency region.

This paper proposes a new estimation method of the maximum torque ampere (MTPA) current phase at low-speed based on an "Ld model", which is a mathematical model that is robust to magnetic saturation for interior permanent magnet synchronous motors. In general, sensorless control techniques based on high frequency signal injection methods have been applied at low-speed drive. Those methods can guarantee the reasonable torque control performance even at zero speed. In addition, most of methods have robustness to motor parameter variation. However, the MTPA control in those methods requires q-axis inductance, which varies significantly owing to magnetic saturation. Therefore, a parameter mismatch may occur, which decreases motor efficiency and the operation range is narrowed. As mentioned above, we propose a position sensorless MTPA control method based on the Ld model.

This paper presents a new position sensorless control method for high power density IPMSMs that has non-sinusoidal inductance spatial distribution. In standstill and low speed region, high-frequency signal injection method is generally utilized for rotor position estimation. However, to apply conventional method for high power density IPMSMs having non-sinusoidal inductance spatial distribution is difficult because the methods are using the value of phase inductance spatial distribution assumed to be sinusoidal. In order to realize position sensorless control with these IPMSMs, the position sensorless method based on pattern matching has been proposed [1], [2]. The pattern matching method has a limitation of operating region which is not clarified. This paper clearly presents the operating region that could utilize pattern matching method. Also a new method to estimate the rotor position is proposed in order to expand the operating region.

This paper presents the reduction method of torque ripple in position sensorless control at standstill/low-speed region of the wound-field synchronous motor with double three-phase wound stator for Integrated Starter Generator (ISG). High-frequency signal injection method which is commonly used for PMSMs is selected for the test motor's position sensorless control. Due to the injected signal, a large torque ripple is generated on the output torque. As our target machine, Wound-field Synchronous Motor with Double Three-phase Wound Stator, has two sets of three-phase windings, we proposed a method by injecting signal to the set of windings in the opposite sign to reduce the torque ripple. The proposed method can realize position sensorless control but also reduce the torque ripple significantly. The effectiveness of the proposed sensorless control method is shown by actual experiment.

This paper presents the position sensorless control for switched reluctance motor (SRM) drive having improved performance via adaptive self commutation instant tuning (ACT). The narrow voltage pulses with suited frequency and duration are injected into an un-energized phase winding via the PWM channel. The resulted amplitude modulated winding currents are sensed and signal processed to yield the observed Hall signal for sensorless control. The determination of key parameters of the proposed sensorless control scheme and the effects of resulted amplitude modulated winding currents are analyzed. No external injection circuit and the motor parameters are required. The observed speed is obtained from the sensed four winding currents. The motor is first started in stepping motor mode, and then it is changed to the sensorless SRM mode as the speed is raised to a suited value. To improve the torque generating capability, an adaptive self commutation control scheme with the identified winding inductance is developed. Experimental evaluation shows that the developed position sensorless SRM drive possesses good driving performance within a reasonably wide speed range.
