Direct torque control (DTC) is one of the most prominent control techniques used by permanent magnet synchronous motor (PMSM) drives in industry applications. Nevertheless, the presence of hysteresis controllers and inaccurate voltage switching table in traditional DTC results in higher torque and flux ripple. This study proposes an enhanced DTC functioned Surface‐mounted PMSM (S‐PMSM) drive with mitigation of torque and flux ripple. The operation relies on generating the reference voltage vector (VV) in a stationary reference frame, which supports control of torque and flux without hysteresis controllers. The reference VV generation is simple and does not affect control robustness. The position of reference VV in a sector is used to build the voltage vector (VV) switching table. As a result, the application of nearest discrete VV to reference VV produces optimal torque and flux control. Moreover, redundant switching combinations of null VV are effectively used for possible minimization of switching frequency of two‐level voltage source inverter (VSI) supplied S‐PMSM drive. Therefore, proposed DTC gains improved S‐PMSM drive response along with switching frequency reduction. In dSPACE‐RTI 1104 platform, experimental response of S‐PMSM drive under various operating conditions have been depicted to highlight the proficiency of proposed DTC in comparison with existing DTC.

“…Since permanent magnet synchronous motor (PMSM) and Li-ion battery are increasingly applied in EV because of their advantages such as light weight, small volume, and high power density, most resent researches of EV are based on these devices and their operating characteristics. 4 For PMSM control strategy, the proportion-integral (PI) controller has been widely used because of the simple structure and easy realization. However, the limitation of the bandwidth causes that the rapidity and the stability of the control system cannot be ensured at the same time.…”

Battery is the core equipment of the electrical vehicle (EV), battery life, and performance are critical to EV. Only motor variables are considered in most model predictive control (MPC) strategy in which battery indexes are neglected. A model predictive speed control (MPSC) strategy with adjustable C-rate of battery is proposed in this paper on EV with permanent magnet synchronous machine (PMSM). The rest capacity of battery is involved in the cost function, and the operating speed is related to the rest capacity of battery which adjusts the C-rate of the discharging currents further to protect battery. As the EV runs, the C-rate is decreased step by step according to the improved cost function, and the energy is saved to prolong mileage. The benefits of the proposed method including discharging capacities and operating mileage are corroborated by the simulation and repetitive experimental results under same conditions.

Offshore wind power generation system's reliability is always a challenging task. To solve the current sensor offset fault problem in the electric powertrain for the offshore wind power generation system, in this paper, a current-detection based sensor offset fault diagnosis method is proposed. The proposed method adopts four fixed measuring points for the estimation of the offset values, which does not require any modifications to the traditional PWM generating strategy. Therefore, the total harmonic distortion (THD) of the drive is not increased by using the proposed offset fault estimation method. The offset fault parameters of the powertrain system are obtained by analyzing the detected current sensors in the aforementioned four sampling points directly. No complex observers nor filters are needed for the signal processing, resulting in computational burden reduction. Experimental results on a 1 kW PMSG system demonstrated the effectiveness of the proposed strategy, which show that the current sensor offset faults can be estimated accurately, and the adverse effects can be eliminated.
