TL;DR: In this article, a novel flux-weakening control combined with magnetization state for the hybrid permanent magnet axial field flux-switching memory machine is presented. And the proposed control strategy is addressed from multiple aspects including the control mechanism, the current distribution strategy, and the voltage and current trajectory.

TL;DR: In this paper, a segmented control method of permanent magnetic linkages of a stator permanent magnetic type memory motor is presented, in which rotation speed is calculated according to direct current bus voltage Udc, the rated phase current In, and the quadrature axis inductance Lq(j) and the permanent magnetic linkage phipm (ifj) of the jth kind of magnetization state.

TL;DR: In this paper, a permanent magnet synchronous motor control algorithm for improving the transient stability of a small capacity DC bus capacitor voltage was proposed, which adjusts the given component of the direct-axis current based on the difference between the DC bus voltage and the absolute value of the grid voltage, and adopts an internal model controller or a repetitive controller as a current controller to realize the fast tracking of period demand signals by d-q currents of the motor.

TL;DR: In this paper, a stator permanent-magnet type memory motor direct torque control method was proposed. But the method only needs two hysteresis controllers and a speed regulator, and the influence on system performance due to motor parameter changes due to magnetization states are relatively small.

TL;DR: In this article, a high efficiency and wide-range speed control method for a stator permanent magnet type memory motor was proposed, which comprises the steps that the area where the motor rotating speed is located is judged through an area judging module, and different current distribution modes are adopted in different areas according to a division control strategy.
