摘　　要：为提高电动汽车增程器无刷直流发电系统的动静态性能,提出通过控制电磁转矩来快速保持系统输出电压的稳定。对无刷直流发电系统直接转矩控制的理论依据进行了推导,研究了无刷直流发电系统直接转矩控制的原理,指出通过选择交轴分量最大的电压矢量作用于电机,可迅速控制电磁转矩。分析了电压矢量的特点,建立了无刷直流发电系统直接转矩控制电压矢量选择表。仿真和实验结果表明,采用直接转矩控制的无刷直流发电系统具有优良的动、静态性能。In order to improve the dynamic and static performance of the brushless DC generator system in range extender of electric vehicles,it was proposed that the stability of the output voltage of the system should be quickly maintained by controlling the electromagnetic torque.The theoretical basis of direct torque control(DTC)for brushless DC(BLDC)power generation system was derived,and the principle of DTC was studied.It was pointed out that the electromagnetic torque could be changed rapidly by selecting the voltage vector with the largest q-axis component acting on the motor.The characteristics of voltage vector was analyzed,and the selection table of voltage vector in direct torque control for brushless DC generation system was established.The simulation and experimental results show that the brushless DC generation system with direct torque control has excellent dynamic and static performance.
