“…When the PMSM speed exceeds the rated speed, the Back Electromotive Force (B-EMF) generated in the winding, caused by a permanent magnet flux on the rotating rotor in the lumen of the stator windings, can increase beyond the limit of the voltage of the inverters. For motors that do not use permanent magnets, such as induction motors, reducing the current rotor windings can reduce the BEMF voltage [13][14][15]. Unfortunately, this way is not possible with rotor motors that use permanent magnets.…”

The paper proposes a new speed control method to improve control quality and expand the Permanent Magnet Synchronous Motors speed range. The Permanent Magnet Synchronous Motors (PMSM) speed range enlarging is based on the newly proposed power control principle between two voltage sources instead of winding current control as the conventional Field Oriented Control method. The power management between the inverter and PMSM motor allows the Flux-Weakening obstacle to be overcome entirely, leading to a significant extension of the motor speed to a constant power range. Based on motor power control, a new control method is proposed and allows for efficiently reducing current and torque ripple caused by the imbalance between the power supply of the inverter and the power required through the desired stator current. The proposed method permits for not only an enhanced PMSM speed range, but also a robust stability in PMSM speed control. The simulation results have demonstrated the efficiency and stability of the proposed control method.

The induction motor for electric vehicles needs to be able to work at high speeds, so field-weakening control is necessary. Compared with the traditional 1/ωr method that can only suit no-load, voltage closed-loop control has better performance in outputting the maximum torque. Besides, sensorless control makes the system less costly and more robust, but most studies on it focus on low speeds. This paper introduces a new control structure to better fit the application of electric vehicles, and the performance of the speed adaptive flux observer is analyzed in detail. Matlab/Simulink results verify the validity of the proposed theory.

“…In the motor drive system powered by storage battery or super-capacitors used in electric vehicles, two schemes are generally adopted to increase the motor speed: flux-weakening control and increasing the DC-link voltage. Compared with the surface PMSM, the interior PMSM is more suitable for the flux-weakening speed-rising due to the reluctance torque produced by the inconsistent rotor inductance between the direct axis and quadrature axis [5,6].…”

The permanent magnet synchronous motor (PMSM) running above the base speed requires flux-weakening control, which is usually realized by the direct-axis demagnetization current generated by the vector control, thus leading to a decrease in the system efficiency in the flux-weakening region. In addition, the motor power output range is limited by the inverter output voltage and current level. In this paper, a Z-Source drive PMSM control system with adjustable DC-link voltage was proposed to improve the efficiency of the motor system. The proposed system was experimentally verified. The response time of DC-link voltage is 10 ms and the overshoot is 3%, indicating good dynamic characteristics. Compared with the flux-weakening scheme, the Z-Source inverter scheme can achieve higher efficiency (about 3%) when the PMSM speed was set to 650 r/min.
