| 摘 要： | 本文证明了感应电动机的解耦控制定理,分析了转子电阻变化对解耦控制系统的影响。指出:在电机磁路保持线性的条件下,欠解耦将导致电机负载能力下降,励磁电流在重载时减小;过解耦则有利于电机负载能力的提高,但在负载稍大时使励磁电流增加。在允许的范围内,增大解耦电阻对感应电动机解耦控制系统是有利的。

| Abstract: | Decoupling theorems of induction motor are proved in this paper, effects of rotor resistance variation to decoupling control are analyzed. The theoretical and numerical results show that under the condition that the magnetic circuit of motor remains Linearity, anderdecoupling will Lead on decrease of Load ability in motor, the magnetizing Current is redused at weight Load; Overdecoupling is adopted to increase in load ability of motor, but magnetizing Current will increase at slightly weight Load. It is useful that decoupling resistance is increased in appropriate range. |
