“…The rotor magnetic circuit of the built-in permanent magnet synchronous motor is asymmetric, and the motor changes electrically under the influence of rotor position angle [17,18]. Combined with the double reaction theory of traditional electrically excited synchronous motor, the current, voltage and flux linkage vectors of the motor are converted into rotating coordinate system.…”

In recent years, the application range of electric energy in modern industry has gradually expanded. Permanent magnet synchronous motor has the characteristics of high efficiency and energy saving and has obvious advantages in traction application. In order to achieve good vector control of permanent magnet synchronous motor in the full speed range, Research on model reference adaptive system (MRAS) and pulsating high frequency injection method to construct the permanent magnet synchronous motor vector control system and combined with the flux weakening control algorithm to control the motor under the condition of limited inverter output, so as to realize the sensorless vector control of the motor in the full speed range. The difference between the estimated value of the algorithm and the actual value is compared on the actual experimental platform to verify the feasibility of the control algorithm. The experimental results show that, under medium and high-speed working conditions, the motor speed and rotor position tracking accuracy of MRAS algorithm is high, and the tracking error is less than 0.01rad. The pulsating high-frequency injection method can accurately track the permanent magnet synchronous motor under lowspeed working conditions, the speed error is less than 1n / R / min, and the rotor position error is less than 0.03rad. The static and dynamic performance of the control system is good, It can better deal with the sudden change of motor load. Using MRAS algorithm and pulsating high frequency injection method to control permanent magnet synchronous motor in full speed range is of great significance to improve the speed control performance of permanent magnet synchronous motor.

“…Fast dynamic and low torque ripple are two big concerns in PMSM drive system [1]. Performance of the current loop, however, is directly linked with the dynamic response and electromagnetic torque [2], [3]. So the optimization of the current loop is of a great significance in enhancing the overall performance and should be well studied.…”

“…Moreover, there is a lack of a comprehensive evaluation standard that can effectively measure the decoupling and dynamic response performances of different algorithms, which increases the difficulty of optimal control design. Cui 22 and Yepes 23 have put forward feasible ideas to evaluate the decoupling performances of different current regulators in a three‐phase system by the dynamic relative gain array (DRGA) and integral absolute error, respectively. However, neither of these methods can be extended to strong transient operating occasions of EML, without considering the time response and frequency response dynamic characteristics.…”

Six-phase permanent magnet linear synchronous motor (PMLSM) for electromagnetic launch (EML) system presents the characteristics of a high order, nonlinearity, multivariable, strong coupling, and nonperiodic transient operation in the synchronous rotating coordinate system, posing a great challenge to the dynamic response ability of the current loop. Existing research on current decoupling control (CDC) mainly focuses on cross decoupling within a three-phase system, even though there are neither decoupling methods for multiphase systems nor effective evaluation criteria for the decoupling and dynamic response performances. From this perspective, this paper first presents an equivalent reduced-order complex-matrix dynamic mathematical model of six-phase PMLSM and analyze its transient coupling characteristics during the process of EML. Then, the CDC methods of six-phase PMLSM based on direct compensation and matrix diagonalization principles are realized, respectively, to accomplish the cross decoupling and back electromotive force decoupling within and between different three-phase windings. Finally, an all-round method is proposed, for the first time, to evaluate the decoupling performances and dynamic response performances of different CDC strategies for six-phase PMLSM. Significant superiority of deviation decoupling regulator in decoupling performance and robustness are verified based on high-speed EML experimental platform of six-phase PMLSM.
