| 摘 要： | 针对传统矢量控制系统磁链观测不准,且需要速度传感器的问题,提出了一种基于MRAS磁链观测、转速估计的无速度传感器异步电机矢量控制系统。介绍了磁链观测、转速估计的MRAS结构,并运用Popov超稳定理论推导出了其对应自适应律,建立了实验系统。实验结果表明,该矢量控制系统在启动、调速、稳态运行时具有良好的静、动态性能,是一种高性能的交流调速系统。

| Abstract: | Aim to the problems that the traditional vector control system's flux observation was not accurate and needed speed sensor,based on MRAS flux observation and speed estimation,the vector control system for speed-sensorless induction motor was proposed in this paper.The MRAS structures of flux observation and speed estimation were introduced and the Popov hyperstability theory was used to deduce the corresponding adaptive laws.The the experimental simulation system was set up and the experimental results show... |
