| 摘 要： | 提出一种用于永磁同步电动机的基于磁链误差矢量补偿的直接转矩控制（EFVC—DTC）策略，给出了磁链误差矢量的估计算法，并将该控制策略下的稳态和动态运行性能与常规DTC进行比较。仿真及实验结果表明EFVC—DTC可以使电力开关器件工作在基本固定的频率上，磁链和转矩脉动显著减小，比常规DTC具有更优越的稳态性能，而动态转矩响应几乎与常规DTC相同。

| Abstract: | A modified direct torque control strategy based on error flux linkage vector compensation (EFVC-DTC) for permanent magnet synchronous machines (PMSM) is presented. The theoretical background of EFVC-DTC is introduced and an algorithm to estimate the flux linkage error is proposed. The steady state and dynamic performances of EFVC-DTC have been compared with those of the conventional direct torque control (DTC). The simulation and experimental results confirm that both flux linkage and torque ripples are significantly reduced in EFVC-DTC with a fixed switching frequency while the dynamic torque response is almost as good as the basic DTC. |
