| 摘 要： | 为了克服直接转矩控制在低速区的不足,提出了将直接转矩控制和间接转矩控制相结合的混合控制方法,介绍了两种方法的基本原理和之间数学关系.该混合控制系统采用基于定子磁链和转子磁链的全阶磁链观测器,在低速区采用间接转矩控制,在高速区采用直接转矩控制,从而实现异步电机的全速域调速控制.实验结果证明了该方式的有效性.

| Abstract: | In order to overcome the disadvantages of direct torque control in low speed range,the basic principles and mathematical formulas of the direct torque control and indirect torque control are introduced.Two methods are combined to form a hybrid control system of all speed range.Based on stator flux and rotor flux,a full order flux observer is adopted.In-direct torque control is used in low speed range and direct torque control is used in high speed range.All speed control of induction motor is realized.The e... |
