“…Introducing a new method for learning and estimating the surface inductance in [33], the stochastic MPC method is used for current control of the SRM. Based on the Euler equation [34], next movement position, current and flux-linkage are calculated and the reference voltages will be obtained using the next motor parameters.…”

The linear switched reluctance machine (LSRM) has all advantages of rotary switched reluctance machine including simple and rugged structure, absence of magnetic material and windings on translator, high reliability and appropriate performance over a wide range of speed. Like rotary switched reluctance motor with segmental rotor, segmental translator linear switched reluctance motor (STLSRM) has capability to produce higher output power/weight in comparison to the conventional linear switched reluctance motors. Due to high advantages of the STLSRM drive, various control algorithms including current control, model predictive control, direct force control, universal control and force distribution function are investigated for the first time to control the instantaneous thrust of this motor. Applying these algorithms to a typical three-phase STLSRM, simulation results are presented and they are compared together from the force ripple reduction point of view.

“…Many scholars have already successfully used this method to control the flux and torque in induction machines (IMs) and permanent magnet synchronous motors (PMSMs) [16][17][18][19][20]. There are also some studies in which the MPC strategy is used in SRM [21][22][23][24]. In [21,22] the MPC scheme is presented to minimize the torque ripple.…”

“…In [23], a predictive current control based on deadbeat solution was presented to follow the reference phase current with a fixed switching frequency. In [24], an online inductance surface estimator with a stochastic MPC method for SRM was introduced. But both methods need to optimize the waveform of the reference phase current based on the predefined torque waveform, which increases the complexity of the algorithm.…”

In this paper, to solve the problem of large torque ripple in a switched reluctance motor (SRM), a new control strategy based on model predictive flux control is proposed in the direct torque control (DTC) algorithm. First, the flux linkage value in the next period is calculated from the discrete time model of the SRM. Second, to reduce the computation burden and increase the dynamic response, a torque hysteresis controller is embedded in the system to select three candidate voltage vectors for the cost function. Finally, based on flux linkage minimization, the best voltage vector is selected and applied to the system. The proposed direct torque and predictive flux control (DTPFC) method perfectly suits the nonlinear magnetic characteristics of SRM, and shows better steady‐state and dynamic‐state performances compared to DTC. Furthermore, since DTPFC has only one variable in the cost function, the huge task of obtaining the best weighting factor is eliminated. Simulation and experiments are carried out on a three‐phase 12/8 SRM with the proposed control algorithm and DTC. The results demonstrate the validity of the new control approach. © 2019 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.

This paper proposes a new drive circuit for reducing the switching current ripples in a switched reluctance motor (SRM). The authors have already presented an instantaneous flat torque control for SRMs, and confirmed its effectiveness through experimental results. However, the switching current ripples also cause torque ripples, and therefore, the current ripples should be decreased to reduce the torque ripples even more. The proposed circuit with parallel capacitor can realize such a reduction. The validity of the proposed drive circuit is verified experimentally. C⃝ 2018 Wiley Periodicals, Inc.
