摘　　要：直接转矩控制从提出到至今已有 2 0多年的历史 ,其间发展了多种直接转矩控制策略。直接转矩控制具有结构简单、转矩响应快以及对参数鲁棒性好等优点 ,但有低速转矩脉动大的缺点。因此大部分被提出的直接转矩控制策略主要为了解决低速转矩脉动问题。对这些控制策略进行了详细的分析和比较 ,并进行了总结 ,这对于将来进一步研究直接转矩控制提供了一个很好的参考。Direct torque control was proposed about 20 years ago,and many control strategies have been developed since then. Direct torque control has the advantages of simple structure,high response of torque and being robust to parameters. However,it also has the disadvantage of torque ripples in low speed range. So most of the proposed strategies are used to solve the problem of the torque ripples in low speed range. In this paper,most of these control strategies are discussed and compared detailedly. which is helpful to the further research of DTC.
