“…There are also commercial PMSM drives where the analog signal of the Hall sensors are used without digitization [12]- [15]. It has recently been shown that there are many benefits of using analog Hall sensor signals such as improvement in control performance [16]- [17] and monitoring of PM temperature [18]. It was also shown that airgap eccentricity and local demagnetization in the PMs can be detected with high sensitivity [19]- [20].…”

On-line monitoring and diagnostics of permanent magnet synchronous motors (PMSM) is becoming important with the increasing demand in PMSM applications. Most of the research effort focuses on motor current signature analysis (MCSA) as it can provide remote, on-line monitoring at low cost. However, all types of defects that produce asymmetries in the PMSM rotor or load produce identical rotor rotational frequency components. This is a serious limitation when applying MCSA since it can produce false indications and degrade the sensitivity of fault detection. In this paper, the feasibility of using analog Hall sensors signals to complement MCSA for detection and classification of rotor and load related defects is investigated. It is shown that Hall sensors installed in machines for initial rotor position estimation can be used with minimal hardware modifications, to detect and classify signatures produced by the rotor and load, for cases where MCSA fails. Experimental testing performed on an IPMSM under eccentricity, local demagnetization, and load unbalance conditions show that the reliability and sensitivity of fault detection in PMSM systems can be improved at low added cost.

“…The most common control methods include vector-or field-oriented control, scalar control and direct torque control [12]. The presented control methods can be grouped into two categories: sensor control method [13] and sensorless control method [14][15][16]. For the sensor control method, the introduction of sensors increases the system cost.…”

High‐speed permanent magnet synchronous machine is often used as a starter generator for a single‐shaft micro‐gas turbine due to its high efficiency and high‐power density. However, when the machine works in the starting mode, it usually needs a complex control system to start since the machine cannot realise self‐starting. Therefore, here, a dual‐purpose rotor sleeve is proposed for the machine to have the starting ability. Furthermore, the dynamic response speed of the machine also can be improved by optimising the electromagnetic characteristics of the sleeve. Taking a 40 kW, 20,000 r/min surface‐mounted permanent magnet machine as an example, the two‐dimensional finite element model of the machine is established. The start‐up time and locked rotor parameters under different sleeve conductivities are studied by the finite element method. In order to find out the reason for the change of starting performance, the rotor eddy current distribution is studied. Furthermore, the starting torque of the machine is decoupling analyzed, and the influence of sleeve conductivity on various kinds of torques are found to reveal the influence mechanism of sleeve conductivity on starting performance. Finally, the correctness of the model is verified by experiments.

The position tracking problem of the electric cylinder, which has internal perturbation, external disturbance, and measurement noise of the output, is studied in this paper. A control method is proposed for achieving high tracking accuracy and tracking velocity for the wheel-legged robot application. Nonsingular fast terminal sliding mode (NFTSM) control is investigated to ensure that the system output can track the reference input in finite time. Besides, extended state observer (ESO) of the active disturbance rejection control (ADRC) is used to estimate the system lumped perturbation and compensated it in the controller based on the terminal sliding mode. This greatly reduces the chattering of the system caused by the gain of the sliding mode switch. Furthermore, tracking differentiator is designed to attenuate the output measurement noise. Simulation and experimental results illustrate that the NFTSM with ESO and TD algorithm, which is presented in this paper, has obvious superiority in the tracking precision and the antijam ability.
