摘　　要：摘要：交流调速在社会生产中起着至关重要的作用。它不但可以调速，也可以把电机制动所发出的电能反馈到电网上，从而实现节能。相比与传统的直流调速而言，三十年的发展让世界的交流调速电动机系统已经有长足的进步。由于当今社会生产效率越来越高。对交流调速系统的调速精度也提出了新的要求和目标。在现有的科技技术水平下，对于交流调速的高性能控制算法主要由矢量控制和直接转矩控制两种。矢量控制较为复杂并且有一定受限条件。所以，本文将按照现有的算法并结合矢量控制和直接转矩控制的优点对无差拍直接转矩控制系统进行研究。AC variable speed plays a vital role in social production. It can not only speed, but also can put the power emitted by motor brake back to the power grid, in order to achieve energy savings. Compared with the traditional DC speed is concerned, three years of development to make the world＇s AC variable speed motor system has made significant progress. Due to increasing productivity in today＇s society, AC speed control system speed accuracy as well as new requirements and goals. Under the existing scientific and technological level of technology for high-performance AC speed control algorithm consists of Vector control and direct torque control of two. Vector control is more complex and there are certain limited conditions. Therefore, this paper will follow the existing algorithms and combining the advantages of vector control and direct torque control of deadbeat direct torque control system research.
