| 摘 要： | 针对传统直接转矩控制低速时电流和转矩波动很大的缺点,提出了一种新型控制方法:在高速区,采用离散占空比控制技术(DRC)设计的开关表方案;在低速区,采用智能控制器控制。仿真结果表明:该方法明显优于常规的直接转矩控制,减少了电流和转矩脉动,提高了系统的控制性能。

| Abstract: | For the big electricity and torque ripple in low speed of normal direct torque control,a new control method was presented.Discrete duty ratio control technology is used for switch table in high region,while intelligent direct torque control is used for the low speed region control.The simulation results show that this method is more effective than the conventional DTC and it reduces the electricity and torque ripples,can improve the system control performance. |
