“…To extend the power and speed operation range which is constrained by a given DC-link voltage, the FW control is usually adopted to weaken the air-gap flux by utilization of [14][15][16]. Based on the conventional decoupling vector control with dq-axis current regulation for a single three-phase machine, the strategies of FW control can be classified into feed-forward [17][18][19][20][21][22] and feedback methods [16,[23][24][25][26][27][28][29][30][31][32]. The FW control of the feedforward method has the advantage of excellent dynamic performance; however, the accuracy of FW current from the feed-forward method relies heavily on the accuracy of machine parameters, such as the flux-linkage and inductances, which might vary with loads and temperature [18,33,34].…”

“…Nowadays, electric vehicles (EV) are widely used to improve efficiency and reduce greenhouse gas emissions by internal combustion engines [1]. There are many EV manufacturers involved in the production of electric vehicles, such as Benz, Tesla, Honda, and Toyota [2]. Electric vehicle systems are more efficient and have a more comprehensive range of speeds than vehicles using internal combustion engines.…”

“…However, under certain operating conditions in some electric vehicles, it is also required to accelerate the engine to above-rated speeds. Therefore, running in the magnetic field is one criterion for evaluating current electric cars [2]. There are two main types of PMSM mentioned in velocity control: IPMSM and SPMSM.…”

This paper proposes an advanced flux-weakening control method to enlarge the speed range of interior permanent magnet synchronous motor (IPMSM). In the deep flux weakening (FW) region, the flux linkage decreases as the motor speed increases, increasing instability. Classic control methods will be unstable when operating in this area when changing load torque or reference speed is required. The paper proposes a hybrid control method to eliminate instability caused by voltage limit violation and improve the reference velocity-tracking efficiency when combining two classic control methods. Besides, the effective zone of IPMSM in the FW is analyzed and applied to enhance stability and efficiency following reference velocity. Simulation results demonstrate the strength and effectiveness of the proposed method.

“…In the constant apparent power mode, the limit of bus voltage must be satisfied by reducing the rotor flux amplitude [10]- [12]. At present, the research of field-weakening control mainly focuses on how to achieve the maximum torque control in the field-weakening mode at voltage and current limits [13]- [16]. There are three kinds of field-weakening control algorithms for induction motors.…”

Maximum torque per amper (MTPA) control can realize the minimum copper loss control of induction motor, which is often applied below the rated speed. In this paper, MTPA control is firstly extended from the constant torque mode to the constant apparent power mode and the constant voltage mode, and realizes MTPA control of induction motor in the whole speed range. Firstly, this paper establishes a MTPA-based nonlinear optimization problem in the whole speed range. Then, this optimization problem is analyzed and the analytical expressions are obtained for three different modes. Finally, finite control set-model predictive current control is adopted in this paper to achieve the fast stator current tracking. In the experimental part, the proposed algorithm is compared with the classical control strategy in this paper. The experimental results show that for the light load, the proposed algorithm reduces the stator current magnitude and improves the efficiency of induction machines.
