“…Therefore, the direct torque control (DTC) method with fault tolerant capability has been proposed for the alternating current (AC) machines under open-circuit fault. The space vector reconstruction method is used in [37] under the open-circuit condition. This method makes a new area division of the stator flux linkage vector and gives a new switch table, and is found to improve the control capability of the electromagnetic torque under the open-circuit condition.…”

The multi-tooth fault tolerant switched-flux machines (MTFTSFM) providing both excellent fault tolerant capability and relatively high torque density are good choices for high reliability applications. A rapid control of the electromagnetic torque under open-circuit fault can always be achieved by the direct torque control with voltage vector reconstruction (RDTC); however, with respect to the rotor speed, its dynamic performance is still impacted by the proportion-integration (PI) parameters. Therefore, a torque impulse balance control (TIBC) is investigated in this paper for the MTFTSFM under open-circuit fault to obtain excellent dynamic performance of the rotor speed. During the dynamic state, the electromagnetic torque and the speed can converge at the same time after only one adjustment of the speed by using the optimized voltage vector sequence based on torque impulse balance, thus, achieving the best possible dynamic process for the speed. The TIBC method is carried out on an MTFTSPM machine system, and the correctness and effectiveness are verified.

“…Nowadays, this scheme is widely studied for emergency operation [11][12], and application of FSIs is enlarging to 3-phase induction motors as well as PMSMs and BLDC motors [13][14]. Therefore, the research about FSIs is highly required, especially the scheme of current ripple reduction due to their inherent characteristic by split dc-link.…”

-This paper proposes an analytic model for four-switch inverter (FSI)-driven wye (Y) or delta (Δ)-connected motors with a current ripple reduction algorithm. FSIs employ four switches in controlling three-phase load instead of using six switches. They have split dc-link stage, and due to this inherent structure there exists the voltage difference between upper and lower capacitors, which results in distortion of the inverter output voltage. To study characteristics of FSIs, this paper presents an advanced simulation models of FSI-driven control system for 3-phase motor that can has a wire connection either Y or Δ. In addition, this paper introduces a current ripple reduction scheme that mitigates degradation of control performance due to the voltage difference between the dc-link capacitors. The validity of the proposed method and the analytic model is verified by simulations and experiments carried out with 1-HP induction machine with Y or Δ-connection

“…The squirrel-cage induction generator (IG) has many advantages, such as being brushless, needing low-maintenance demands, and having inherent overload protection capability. The IG has attracted a great deal of interest in stand-alone power systems [4]- [6]. The reactive power consumption and poor voltage regulation with variations in speed and load are the main limitations of the widespread application of IG.…”

“…If the input electromagnetic power is greater than the output load power, the output voltage will increase; otherwise, the output voltage will decrease. Consequently, to keep the output voltage constant, the electromagnetic power should equal the load power if the loss is to be ignored [5], [6]:…”

This paper presents the control and implementation of the dual-stator-winding induction generator for variable frequency AC (VFAC) generating system. This generator has two sets of stator windings embedded into the stator slots. The power winding produces the VFAC power to feed the loads, and the control winding is connected to the static excitation controller to control the generator for output voltage regulation with speed and load variations. On the basis of the idea of power balance, an instantaneous slip frequency control (ISFC) strategy using the information of both the output voltage and the output power is used in this system. A series of experiments is carried out on a 15 kW prototype for verification. Results show that the system has good static and dynamic performance in a wide speed range, which demonstrates that the ISFC strategy is suitable for this system.
