【摘要】：多相感應(yīng)電機具有高效、低轉(zhuǎn)矩脈動,能容錯運行以及更易于實現(xiàn)低壓大功率等優(yōu)勢,特別適合應(yīng)用于電動汽車。針對驅(qū)動系統(tǒng)常出現(xiàn)的缺相故障,基于故障前后定子磁動勢保持不變的原則研究了容錯控制策略,并探討了3次諧波注入后,1、3次諧波之間的磁場耦合及其對電機轉(zhuǎn)矩等性能的影響。為解決滯環(huán)控制產(chǎn)生的轉(zhuǎn)矩脈動和效率下降等問題,電流環(huán)采用了比例諧振控制方式,利用其諧振點附近的高增益,實現(xiàn)了相坐標系下的無靜差控制。構(gòu)建了一套低直流母線電壓供電的五相感應(yīng)電機控制系統(tǒng),通過一相和兩相繞組斷開故障等實驗,研究對比了不同控制策略下電機的性能,及各控制策略中諧波耦合的影響。
[Abstract]:Multi-phase induction motor has the advantages of high efficiency, low torque ripple, fault-tolerant operation and easy realization of low-voltage and high-power, so it is especially suitable for electric vehicles.The fault tolerant control strategy is studied based on the principle that the stator magnetodynamic force remains invariant before and after the fault.The magnetic field coupling between the first and third harmonics after the third harmonic injection and its effect on the torque and other performance of the motor are discussed.In order to solve the problems of torque ripple and efficiency decline caused by hysteresis control, the proportional resonance control method is adopted in the current loop. By using the high gain near the resonant point, the static error free control is realized in the phase coordinate system.A five-phase induction motor control system with low DC bus voltage is constructed. The performance of the motor under different control strategies and the effect of harmonic coupling in each control strategy are studied and compared through the experiments of breaking faults between one phase and two phase windings.
