“…High-order sliding mode control has the characteristics of fast response, insensitivity to disturbance and parameter change, and simple implementation. It is widely used in motor control [22][23][24][25]. In [22], high-order sliding mode control is applied to the nonlinear control of induction motor, which improves the static and dynamic performance of motor speed regulation and enhances the robustness.…”

Because of the current commutation and the double salient pole structure of bearingless switched reluctance motors (BSRMs), the torque and suspension force have large ripples when traditional current control methods are used. According to the special structure of the double stator BSRM (DSBSRM), the direct decoupling of torque and suspension force is realized. Therefore, the DSBSRM can be controlled separately as a conventional 12/8 SRM and a four-poles active magnetic bearing. In order to achieve the suppression of the torque ripple and improve the robustness of speed, a direct torque control (DTC) strategy using second order sliding mode (SOSM) speed controller is proposed. In order to achieve the suppression of the suspension force ripple and rotor displacement chattering, a direct suspension force control (DSFC) strategy is proposed as well. Then the SOSM-DT/DSFC model is established by simulink. The results of simulation show that the torque ripple, suspension force ripple, and rotor radial displacements of DSBSRM can be reduced respectively. Moreover, the proposed control strategy has better robustness and dynamic performance than traditional control strategy.

“…However, most of the literature research focuses on the field of control. Many scholars proposed new intelligent control strategies based on the torque distribution control strategy [5], variable structure control strategy [6], and modern control theory [7,8]. The method of control field increases the complexity of the controller and cost of the motor.…”

Torque ripple is the main cause of motor vibration and noise. In order to reduce the torque ripple of the switched reluctance motor (SRM), a new type of rotor tooth profile is studied, namely adding a semi-oval auxiliary core on both sides of the conventional parallel rotor tooth profile. Using a finite element method, a 12/8-pole SRM was modeled, and an optimal modified model was obtained through parameterized simulation. At the same time, in order to further reduce the torque ripple, the turn-on and turn-off angles of the power converter are optimized, and the torque jump caused by the commutation phase is alleviated. The combination of turn-on and turn-off angles is obtained through simulation calculation, and it can not only significantly reduce the torque ripple of the SRM, but also alleviate the local saturation caused by the double salient pole. This method can reduce the local saturation caused by the double salient structure and the large torque jump caused by the commutation phase. This method is of reference for other double salient motors.

“…In [9], the super-twisting controller (STC) was designed to control the flux tracking and velocity tracking of the motor. In [10], it applies the super-twisting sliding mode control algorithm to the full-bridge inverter, and in [11][12] they use the supertwisting sliding mode control algorithm for the motor speed control system. It is well known that the discontinuous switch function sign(s) causes chattering.…”

In this paper, the second order sliding mode control law was designed based on the super-twisting algorithm and the switching function sign(s) was replaced by the saturation function sat(s) for the torque and flux controller in the permanent magnet synchronous motor double closed loop control system. The stability of the system was proved by Lyapunov function. The traditional direct torque control method and the simulation results of this method were analyzed by using MATLAB / SIMULINK simulation tools. The results show that the torque ripple based on the direct torque control system of the super-twisting algorithm is reduced by 4 times compared with the traditional direct torque ripple. Speed response time is shorter. Speed fluctuation is smaller. System stability has improved significantly.
