直接转矩控制同步电动机励磁电流的控制研究
Study of direct torque control excitation current of synchronous motor
摘要
Abstract
Aimed at the problem of synchronous motor direct torque control method in its dynamic process of torque angle, the control method of the synchronous motor work in unity power factor by adjusting the excita-tion current is put forward. In order to obtain a wide speed range, based on direct torque control method and the constant torque excitation current control, the control method of speeding up for weak magnetic is found. And finally, the regulating action of excitation current upon the operating state of motor in full speed range is verified through simulation, thus the results are consistent with the theoretical analysis.关键词
