A kind of speed sensorless permanent magnet synchronous motor control system used complex speed identify arithmetic

本文针对永磁同步电机控制系统,提出了一种将模型参考自适应(MARS)转速辨识算法与直接估算转速算法相结合的转速辨识复合算法,并构建了复合仿真模型。结果表明,采用复合算法的系统性能优于只采用单一的MARS转速辨识算法的系统性能。

Aiming at the permanent magnet synchronous motor control system, this paper bring a kind of complex speed identify method forward, which combine with the Model Reference Adaptive System （MRAS） speed identify method and the direct speed estimating arithmetic, and then a compound simulative model is builded. The result show that the performance of compound model system is better than the model only use the Modal Reference Adaptive System （MRAS） speed estimating method＇s.
