摘要:通过分析转矩变化规律,研究不同电压矢量对转矩的变化所产生的影响,提出了改进的磁链和转矩的双层滞环方案。解决了传统直接转矩控制存在的低速转矩波动大的问题,方案简单、易于实现。仿真结果表明,采用该方案,能在不降低系统动态性能的情况下拓展系统的低速运行范围,降低转矩波动,提高电机的低速转矩。

Abstract: A new improved doublelevel hysteresis controller of flux and torque for the direct torque control of an induction was proposed, which has solved high torque ripple in low speed of conventional direct torque control, based on analyzing the rule of torque varying, the effect on torque changing of different voltage vectors. The proposed method was simple and eased to realize. Simulation and experimental results indicate that the improved controller extends the range of low speed operation and reduces the torque ripple , and increase the low speed torque while maintains the dynamic performance.
Key words: DTC; doublelevel hysteresis controller; induction motor
