“…In [9], an observer combined with Hall signals was proposed to obtain the back electromotive force (EMF) by using the stator voltages and currents, and then the high-precision position can be achieved. On the basis of [9], some improvements were made in [10][11][12][13][14] to enhance performance of the observers. In [15], a vector-tracking observer was presented, and detailed analyses were made and some improvement measures were presented in [16][17][18][19].…”

Low resolution Hall-effect sensors have been commonly applied in PMSM drives for the reason of cost and volume. Generally, rotor speed and position are estimated inaccurately due to the installation error of the sensors. The inaccurate position degrades the performance of current control and also increases torque ripples, which aggravates mechanical vibration and noise. An improved dual observer is proposed in this paper to suppress the impact of misplaced Hall-effect sensors and improve estimation accuracy. By a cascading dual Luenberger observer and combining feedback decoupling control, the low-order noises produced by the deviation of Hall signals are effectively suppressed. The effectiveness of the proposed method is verified by experimental results.

Because a modular motor drive is composed of multiple identical pole drive units and controllers, it can be considered as a multi-agent system. This makes modular motor drives particularly interesting during faults, when the remaining healthy agents assure the continuity of operation. Nevertheless, for some crucial information such as the rotor position, these drives still rely on a single sensor which introduces a single point of failure. In this work, this single high-resolution position sensor is replaced by multiple binary, low-resolution position sensors. A vector tracking observer algorithm, implemented in the different controllers, processes this low-resolution sensor data into a position estimate. Subsequently, these position estimates of the different agents are exchanged with other agents using a distributed averaging algorithm. For this latter approach, it is shown in this work that it improves the position estimation under healthy conditions as well as during agent malfunctions. The concept is demonstrated on a modular axial-flux permanent magnet synchronous machine with fifteen pole drive units, each equipped with a low-resolution position sensor, that are assigned to five agents.

“…Meanwhile, as a practical compromise, the sensor board fixed to the stator including inexpensive binary Hall sensors (<$2) is often employed since it requires very little cost and volume in comparison with shaft-mounted sensors. While it can still provide discrete absolute rotor position information [6,7]. However, due to the extremely low resolution, the position error will be inevitably large if Hall sensors' signals are directly used, which will also worsen the current control performance.…”
