<span>This article presents an improved Direct Torque Control (DTC) technique with space vector modulation (SVM) for a five-phase permanent magnet synchronous motor (PMSM) using a sliding mode speed control (SMC).The proposed control scheme of the five-phase PMSM combines the advantages of SMC control and the SVM algorithm. The SMC method insensitive to uncertainties, in particular external disturbances and parameter variations. In this paper, the SMC controller is used to control the rotor speed of the five-phase PMSM based on DTC-SVM. The rotor speed response, torque and stator flux are determined and compared with traditional control method. The simulations results confirm the validity and effectiveness of the proposed control technique in terms of performance and robustness against machine parameter variations (inertia variation). The efficiency of the proposed method applied on the five-phase PMSM is verified by the MATLAB/Simulink.</span>

“…In view of the drawbacks of the conventional DTC algorithm, many efforts have been made in literature to improve the control performance of DTC. The main solutions can be divided into three types: changing the switch table or torque hysteresis adjustment; adding SPWM to the DTC strategy and model predictive control (MPC) combined with torque control [15][16][17][18][19][20][21][22][23] .…”

“…The first control strategy to change the switch table or torque hysteresis regulation is mainly achieved by designing a complicated hysteresis regulator or increasing the number of the voltage vectors [15][16][17] . In the second method, the space pulse modulation (SVM) is added to the DTC strategy, which is mainly through the integration of vector control and DTC [18][19][20] . In the third solution, model prediction combined with torque control is used to calculate the most appropriate voltage vector through predictive control algorithm, thus eliminating the design of switch table [21][22][23] .…”

Five-Level Hysteresis DTC of Open-End Winding Permanent Magnet Synchronous Motors With Zero-Sequence Currents Suppression and Torque Ripple Reduction

Direct torque control (DTC) systems for open-end winding permanent magnet synchronous motors (OEW-PMSM) with common DC bus generate zero sequence currents (ZSC) and large torque ripple, resulting in increased system loss and poor operating characteristics. In this paper, a DTC based on five level torque hysteresis (FLTH) is proposed to improve the system performance. Firstly, an online calculation and selection strategy based on switch table is designed to suppress ZSC. By analyzing the composition of zero sequence voltage and using the double vector method to suppress it, the ZSC can totally be suppressed in theory, without affecting the system performance. On this basis, this paper proposes to add FLTH to DTC to reduce torque ripple. FLTH can not only effectively use many voltage vectors, but also reduce torque ripple. In the case study, the torque ripple rate has been reduced by 53%. Through simulation and experiment, the conventional DTC and the FLTH DTC are compared, and the results prove the validity of the proposed strategy.INDEX TERMS Direct torque control (DTC), open-end winding permanent magnet synchronous motor (OEW-PMSM), five-level torque hysteresis (FLTH), zero-sequence current (ZSC), torque ripple.

This work presents an improved Direct Torque Control (DTC) method for a 5-phase interior permanent magnet synchronous motor (5P-IPMSM) based on space vector modulation (SVM) and fuzzy logic (FL). In this proposed DTC control, we replaced the traditional proportional-integral (PI) by the FL controller. The main goal is to improve system performance by minimizing the ripple of the stator flux and the torque ripples. The proposed control technique applied on the 5P-IPMSM is verified by Matlab/Simulink software followed by an analyzed and compared to verify the effectiveness of the proposed method. Many improvements have been made to the stator flux ripples, torque ripples, rise time and the robustness to disturbance.
