中文摘要:采用矢量控制技术控制电机,在连续控制上有很大的优势,但它对被控电机的参数要求很高,且计算繁琐。直接转矩控制技术计算相对简单很多,它简化了控制结构,直接对转矩和磁链进行砰-砰控制,低速性能较差,调速范围受到比较大的限制。鉴于上述两种控制方法的优缺点,本文提出一种新型三相电机控制方法,仿真表明,这种新型的控制方法继承了矢量控制和直接转矩控制的部分优点,又抑制了这两种控制方法性能上的一些不足。

A Control Method for Asynchronous Motor Based on the Current Vector and Switching Form
Abstract:Using the vector control technology to control the motor in continuous control have a great advantage, but it is charged with motor parameters demanding and tedious calculations. Direct Torque Control technology is relatively simple to calculate a lot, it simplifies the control structures, direct torque and flux bang-bang control, poor low-speed performance, speed range is subject to restrictions. In view of the advantages and disadvantages of the two control methods, this paper proposes a new type of three-phase motor control method, the simulation results show that this new control method inherited some of the advantages of the vector control and direct torque control, and inhibition of these two control a number of deficiencies in the method performance.
