Design of the Speed Sensorless Vector Control System for Induction Motor

本文针对由PWM逆变器供电的感应电动机,给出了其定子电流控制器、转子磁链状态观测器、转速及定转子绕组电阻辩识器和矢量控制器的设计方法。它们为无速度传感器感应电机矢量控制系统的实现提供了手段。仿真和试验结果证明了其可行性。

For induction motor supplied by the voltage source type inverter this paper presents a novel speed seusorless vector control straegy which first gives a complete method to design the AC adjustable speed system. The strategy includes the stator current controller,the rotor flux observer, the rotor speed identificator, the rotor winding resistence identificator and the vector controller. The simulation and experiment results show that proposed strategy is effective.
