“…This paper also investigates the detection and control of a fault in a one-phase current sensor. Previous research used a current estimator to evaluate the current sensor error, and an adaptive threshold was used to detect and diagnose the faulty condition [23,24]. In a faulty condition, the estimated current replaces the faulty current.…”

This paper proposes a speed-loop periodic controller design for fault-tolerant surface permanent magnet synchronous motor (SPMSM) drive systems. Faulty conditions, including an open insulated-gate bipolar transistor (IGBT), a short-circuited IGBT, or a Hall-effect current sensor fault are investigated. The fault-tolerant SPMSM drive system using a speed-loop periodic controller has better performance than when using a speed-loop PI controller under normal or faulty conditions. The superiority of the proposed speed-loop-periodic-controller-based SPMSM drive system includes faster transient responses and better load disturbance responses. A detailed design of the speed-loop periodic controller and its related fault-tolerant method, including fault detection, diagnosis, isolation, and control are included. In addition, a current estimator is also proposed to estimate the stator current. When the Hall-effect current sensor is faulty, the estimated current is used to replace the current of the faulty sensor. A 32-bit digital signal processor, type TMS-320F-2808, is used to execute the fault-tolerant method and speed-loop periodic control. Measured experimental results validate the theoretical analysis. The proposed implementation of a fault-tolerant SPMSM drive system and speed-loop periodic controller design can be easily applied in industry due to its simplicity.

“…In [30,31], the effects of inaccurate DC bus voltage in three-phase AC/DC converters are analyzed and voltage compensation strategies are proposed to solve the voltage mismatch. Several voltage observers are built to estimate the DC bus voltage [32][33][34][35][36][37][38][39][40]. In automotive systems, a nonlinear DC bus voltage observer was designed to deal with the information of real-time PWM cycles in both traction and charger modes [32].…”

In this paper, the effects of inaccurate DC bus voltage measurement are analyzed to model predictive current-controlled permanent magnet synchronous motor (PMSM) drives. It is found that the selection of the optimal space vector is affected by inaccurate DC bus voltage measurements, and the shortest distance principle is proposed to evaluate the effects. With the under-voltage measurement, the actual q axis current is always larger than the reference value, and PMSM may be damaged by the over-current phenomenon. However, the actual q axis current is always smaller than the reference value with the over-voltage measurement, and the rated torque capacity cannot be properly used. The effects of the over-voltage measurement are more serious than those of the under-voltage measurement. Additionally, the larger DC bus voltage measurement error can result in more serious effects than with the over-voltage measurement. Considering the limited variation range of the actual DC bus voltage, the rated value can be set as the measured value and the effects can be neglected. However, the effects should be taken into account if the variation range of the actual DC bus voltage is large. All the theoretical analyses are verified by experimental results.

“…In some safety-critical systems such as aerospace or automotive industry, a fault-tolerant drive with its capability of providing reliable post-fault operation is essentially required [3]. In literature, the fault-tolerant control (FTC) topic is very large [4]- [7]. Because of its highest percentage of registered failures in practice, faulty events within the power inverter resulting in single-phase open-circuit faults (SOF) is the main scope of this paper [8], [9].…”

AbstractThis paper presents a comparative performance study of three typical fault-tolerant control (FTC) topologies [split-capacitor (SC), extra-leg split-capacitor (ELSC), and extra-leg extraswitch (ELES)] for direct torque control (DTC)-based threephase permanent magnet (PM) brushless AC (BLAC) drives under single-phase open-circuit fault (SOF). The advantages and limitations of these FTC schemes are theoretically compared and empirically validated. To achieve reliable postfault operations, control issues associated with VM-based flux estimators employed for DTC-based BLAC drives under SOF are demonstrated and relevant remedies are proposed. It is shown that although the ELES scheme can maintain the normal based speed, 6 of its 8 switching states cause phaseto-neutral short circuit in one or both two remaining phase windings resulting in high current harmonic values. Besides, during its implementation, the full DC-link voltage value is always applied to the non-short circuit phase windings leading to high possibility of winding insulation damage. Thus, for a compromise of the normal based speed by a factor of 3/2, the ELSC drive should be used to avoid these issues. Furthermore, in the low-speed region up to half of the rated speed, the lowest copper loss, current harmonics, and torque ripples can be obtained by utilizing the SC drive.
