| 摘 要： | 在研究按定子磁场定向控制系统中 ,采用定子磁链观测器控制磁链 ,认为定子电阻是恒定不变的。而在实际电机运行过程中定子电阻由于发热等条件因素的影响会一直变化。通过讨论定子电阻的变化对控制系统性能的影响的理论分析 ,指出定子电阻在按定子磁场定向的控制系统中低频时对系统影响较大 ,同时应用MATLAB的SIMULINK进行模仿定子电阻变化相关仿真。

| Abstract: | In the newcontrol strategy of stator flux oriented control of induction motors,the flux is controlled by the stator flux observer,in case that the stator resistance of the motor is invariable.But in the running process of the motor,the stator resistance will always change because of heating and other reasons.The influence of stator resistance in the flux orientated models and control strategies of induction motors are discussed.The research indicates there are more influence in low speed in the system.It is proved by simulation using the SIMULINK of MATLAB. |
