| 摘 要： | 为解决在中高压领域无速度传感器矢量控制速度辨识差的缺点,基于三电平电压源型逆变器,提出了一种异步电机无速度传感器矢量控制方案.该方案采用间接矢量控制(IFOC)策略,以模型参考自适应(MRAS)方法构造速度辨识系统,并在新型三电平空间矢量脉宽调制(SVPWM)简化算法基础上,运用MATLAB/Simulink实现对三电平异步电机无速度传感器矢量控制系统的仿真研究.仿真结果表明,所述控制方法正确有效,该系统具有较好的稳态特性和动态响应能力.

| Abstract: | In order to improve the performance of speed estimator in middle-high voltage field,a speed sensorless control scheme for asynchronous motor fed by three-level inverter was proposed.The scheme adopted indirect field oriented control(IFOC) method,three-level simplified SVPWM algorithm,and model reference adaptive system(MRAS) to realize the sensorless vector control simulation of asynchronous motor fed by three-level inverter in MATLAB/Simulink.The simulation results showed the system has good static and dyn... |
